PowerMatch Experiences

Sign me in for the beta as well.

Hi all,

So i tried a lower gear as suggested above and this seemed to help somewhat. However todays ride was really frustrating and I have 2 main issues.

  • Powermatch seemed to work pretty well when on the ‘overs’ however when it dipped to the unders it seemed to try to hold me 50-20 watts below my target power?

  • Not as large issue but the rest intervals again seem to hold me 50 ish watts below the target?

My set up is assioma uno and Kickr snap.

Appreciate any help on this,
Jack

sign me up for the beta, happy to help with testing.

@Nate_Pearson Count me in for testing this beta! I always run on my Windows Laptop!

Using my Assioma Duos & H3 in powermatch there is definitely a lag in the trainer adjusting to large power increases. When It steps up 100+ watts with cadence at +/- 1-2 rpm it can take the system 5-7 seconds to get up to power. With SSB2 next up, I imagine I will have to jump pretty hard to get power up for some of the super short sustained efforts - I haven’t done those workouts with powermatch, only with standard ERG before. Is the new update expected to expedite the trainer’s response time?

If it’s still open, I’d like to give the beta a try!

New power match problem (I think it’s new). Using Ant Plus on the pedals; BT on the Tacx Neo.

When group workout is not the foreground application resistance doesn’t change when the interval changes. It continues locked at the last setting. Making the app foreground will only resume power match after some back pedaling and messing with cadence.

Maybe a silly question, but can you use an external power meter (favero) on a smart trainer in standard/resistance mode? I want the accuracy of the pedals and the silence of the trainer. Have been using dumb trainer (kk road machine) but might upgrade to direct drive trainer.

Yes.

Tried Powermatch this week, Tacx Neo2T with Stages, quite like it, set to 3 sec smoothing, works great, just concentrate on the cadence and the power works itself out (I find if I glance out the corner of my eye the power is spot on, as soon as I look fully, no chance :grinning:)

I was concerned because its a left only PM, my race bikes have dual but I’ve noticed of late my 2-3% imbalance has moved from left to right, so I’m happy to leave Powermatch on. (Just no single leg drills😀)

Just to add another experience to this - had some very interesting/odd results yesterdy during Warlow.

  • Started out with Powermatch on for Assioma Duo pedals controlling Saris H3 trainer
  • During first warmup interval it took the trainer quite a while to come up to resistance (target was around 240W and the first half of the effort the trainer seemed to be set at 220W) Attached is a screen shot of this interval with the first 90s averaged. I know it doesn’t look like it was much below, but it was holding steady at 20+ W under target, which was approaching 10%.
  • After the first warmup, during the recovery before the start of the first interval, target was around 100W and reported power just hung around 140-150W - see second interval screenshot below. Just before the start of the work interval, I decided I wasn’t going to screw with this for the whole workout and turned off Powermatch (you can see at the end of the recovery where power drops to the appropriate target).
  • When analyzing the files recorded with other devices (Pedals recorded in Garmin and Zwift, H3 in TR from first interval onwards) it seems like the H3 was typically reporting within 5% during the work intervals, but majorly off (H3-100W vs Duo-150W) during the rest intervals (see 3rd screenshot). This resulted in massively different Avg Powers for the workout (H3-160W vs Duo-190W) See 4th screenshot.

I would be happy to be a tester this - I am using an Elite Suito and a stages 4iiii left sided meter and have had some issues.

I tried a ramp test experiment today with powermatching and was not really a fan, so I’ll be switching for that most likely. My mental state during a ramp is already too overloaded to see fluctuations of that order when being hammered!

Better off from my experience, the machines react quicker vs a action-reaction-action link of events.
Test with your trainer power, train with your trainer power; don’t moan if it’s -/+ 5w different then what you do outside.

Powermatch is (was) good for budget trainers with power estimates that where pretty off

Hi all,

I just wanted to check my understanding of how this works on my ride today.

Due to recent issues i’ve been having with powermatch i decided to do intervals with consistent power using powermatch and over and unders without. Today was my first over and unders.

  • For the first interval i set my power meter to use cadence only. My understand is this then uses the trainer virtual power?

  • For the following intervals i then turned the power meter back to normal but turned off powermatch. I then covered the displayed wattage so it wouldn’t put me off or distract me. My understanding is this will then record the actual wattage from my powermeter but continue to be controlled by the trainer virtual power? If this is the case this would then show me the difference between my trainer and power meter?

  • From the ride data below it appears my trainer underestimates the power? This would make sense as my last test 4 weeks ago was using the trainer with no power meter. Since adding the power meter and power match rides have felt easier and this was the first over and unders to feel like over and unders.

Thanks in advance for helping me with this

Virtual Power is used to estimate power from a standard trainer, but since you have a smart trainer, it doesn’t apply here. In this case, we take the power readings directly from your trainer’s onboard power measurement device.

Yes - this will show the power from your PM, be controlled by your trainer, and will show you the difference between the two.

Yep. According to the data, your power meter reads higher than your trainer. Be sure that the trainer is calibrated and your power meter has been recently zeroed if you want to accurately compare the two :+1:.

Cheers!

Thanks, appreciate your help!

Adding myself to this thread to get scooped up in the Beta when it’s released.

There is a difference in slope on my PM vs the trainer that causes deep valleys after VO2Max intervals that is slow to get out of. I end up with about 1 min of almost no trainer resistance after high effort intervals. I can turn off Powermatch, but then I get higher work intervals (no thanks!).

Started TrainerRoad today.
I have to say I an not a particular fan of erg mode.
I have a set of Elite Arion Digital B+ rollers which are quite hard to calibrate.
However, I used them on Zwift coupled with a Powertap G3 wheel and things work quite smoothly when I select the rollers as Ant FE-C device and Powertap as the powermeter. This happened both in erg and resistance.
But today’s experience in TraineRoad with the very same setup and powermatch set as auto was very erratic.
I was using Beech and the rollers resistance was all over the place for quite a long time in the beginning of each interval before settling a bit allowing me to stay within fairly acceptable power levels.
Is there something I could do to make it work better? I also have a dumb trainer that I intend to use for high intensity efforts but I was assigning the rollers for easier and less demanding workouts like Baxter.
