Elite Direto user here. I feel that the power readings from my intervals fluctuate very much, check out the image below:
Is this similar to other users on here? I try to focus on keeping a steady cadence and always run the bike in the small chainring and middle of the cassette.
Feel free to post screenshots of your readings and also what smart trainer you are running 
Looks normal. Reinstein, zoomed in, Kickr 2017.
The Kickr has an option to smooth data, but itās artificial and not really whatās happening.
Yup, the smooth lines you see in other peoples profiles are only āvisualā power smoothingā¦ their real power output probably looks a lot more like yours ^
Looks perfectly normal to me.
Agree - looks good. Itās not as āprettyā as a smoothed out on, but it looks very similar to how mine look on a Tacx Neo.
Good to hear, thanks everyone for your replies!
It looks like dumb trainers are more accurate
And I agree with that. I had one without erg mode and was easier to keep smooth diagram but finnaly I didnāt want to change my gears so bought Drivo II and graphs look even more chaoticā:blush:
Hereās my ride today with ERG mode and power match
I spend a decent amount of time working on smoothing my pedal stroke, so even though that graph is from my P1 power meter it seems fairly smooth. Iām unclear how much of it is hardware and how much is the rider - very hard to test without showing up and riding someone elseās setup
I guess the point I was trying to prove is that power output from YOU fluctuates, regardless of whether youāre in ERG or non-ERG mode. If the graph looks smooth then it probably isnāt really whatās going onā¦ Therefore, the criticism thrown at ERG by some people - that it doesnāt simulate real life situations - is irrelevant.
The problem isnāt that I canāt reach the power goals on a dumb trainer, its that I have to very quickly figure out which gear and what cadence I need to get to to meet the power requirement. Thatās where ERG is massively helpful! Once Iāve figured out my gearing and cadence though, there is no reason why my dumb trainer power graph should look any less smooth than an ERG graph.
Iāve recently purchased a TACX Flux smart trainer (after much deliberation) and whilst I find ERG mode āinterestingā and Iād like to think that my power numbers are more accurate, I actually miss having to think about gear selection.
In my experience, being in the right gear and KNOWING which is the right gear in real world situations such as a race for example, can be the difference between competing in the sprint or spinning like a windmill.
Long story short, I miss my gears.
