Ok, I made a short test today: My Rallys are 14W lower than my Kickr Core - didn’t expect that! 
(I calibrated before doing the test.)
How do I even achieve PRs with this difference? 
Maybe I have some imbalance. Need to check my other PM too…
I retested (recalibrated): Now to difference of average watts was only 6W (Rally < Kickr Core). For short times (<5s) the Rallys were higher, for longer times (>30s) it was the other way round.

Yes but your Strava course and segment times are too high because you have cheater pedals. Reported. 
I can’t imagine caring less about something since normally I just get in with some group and race that little pack of 20 in most Zwift events I do anyway.

Busted.
Zwift races are typically short. If you can smash a vo2 effort at the start, another one or two during the race, handle surges, and ride sweetspot for recovery, you’ll do well. Also not to be underestimated, Zwift racing takes some getting accustomed to, e.g., typical race dynamics, course layout, race dynamics for a particular course, drafting, etc…
I’ll add that being fit for a 30min - 1hr Zwift race is very different than being fit for typically longer races in real life.

This. Of course nothing wrong with it, but totally different beasts.
It’s similar to the debate about 100m sprint vs 42 km run …

of course, for the longer ones you must have a great fat metabolism. and it seems that is the only reason to do “high” (relativ) volume.
cause the zwift bois with their low volume they also have a huge oxidative capacity. so it seems mitochondria dont need high volume at all for their improvement.
You seem to be laboring under the misconception that you need to burn lots of fat to get good at burning fat.
Depending on what you mean by “high volume”, no, they don’t.
No i dont believe this. you can also take the carbs away when your ox capacity has the wanted size.
So if you don’t, what did you mean by this? I’m confused as to what your stance is.
“of course, for the longer ones you must have a great fat metabolism. and it seems that is the only reason to do “high” (relativ) volume.”
They don’t mention burning lots of fat to get good at it. You just decided that’s what he(she) meant

You’re right, technically all they have claimed is that you need to do high volumes of training to have “great fat metabolism” (which is also not correct*).
*Example: in the early 1990s, I was a pilot participant in a study examining the effects of high- vs. low-glycogen availability on amino acid metabolism during exercise. The exercise protocol entailed 90 min of exercise at a moderate intensity followed by 60 min at the highest intensity you could sustain. Despite only training 8 h/wk (i.e., (“one lap of Galveston Island and twice on Sundays”), in the low glycogen trial I was able to maintain ~300 W, eliciting a VO2 of ~4 L/min (~75% of VO2max) with an RER of only ~0.7. That’s a “Fatmax” of >2 g/min!

yea but with zero “topend” probably …
two ways:
going hard hard hard + carbs builds both engines. but you will always use A LOT of carbs. unefficient af. not for anything longer then 120’.
going long + carbs builds it also but different. you will get less dependent on carbs and already establish high usage of fat as a substrate at “lower” intensities without the need of fuel manipulation and with the right glycolytic training also the top end is there.
imo

Your opinion isn’t supported by science.

xp is higher valued 
You’re confusing vo2max (total cardiac output) for muscular endurance capacity. Plus the fact that some people get a huge and fast response to training, others start with a much higher innate capacity, and on occasion you get both in the same person.
Unfortunately experience doesn’t mean you understand what’s happening under the hood.

no they have a great muscular oxidative capacity also and they are not just buffering. they clear lactate very well.
xp is good but in my case they also say i know a little xD
Lactate clearance has nothing to do with performance.

lol ok i wish you all the best
Since the thread is off the rails already and my post got no traction…
Any thoughts on lactate clearance, recovery and impact on performance?
In my post linked above there is a YouTube clip from USATF Level II clinic where it is noted that early in the season we should have short recoveries, later in the season longer recoveries (Scott Christensen, the presenter, references the lactate curve as evidence and notes this tends to be “reverse” in what we normally do).
Thoughts?
