This graph looks a bit choppy for erg mode. Did you use the big ring? The small chain ring and one of the larger cogs may get you a little more erg precision.
Iād keep the result. The spikes/troughs in the last few minutes donāt look different than the ones earlier on.
Hopefully youāre in AT, and the AI can set you straight pretty quickly if youāre not right on. Remember that a ramp test can miss your true ftp by more than a negligible amount even if you perform it exactly to specification.

Using largest chain ring in front and smallest in rear ā will take your advice next time. Yes I used erg mode on Wahoo Kickr with Favero Assioma duo pedals (which makes the graph look choppy).
FYI - The TR team recommend using the small chainring and a middle cog so that you get the straightest chainline which will be smoothest and quietest too. Thatās for every ride in Erg, not just the Ramp test.

Thanks. I didnāt know this and will try implementing.

I dont understand why TrainerRoad doesnt use the simple 12 period average for the FTP, from the ramp test. It results in the same value as 75% of the last minute, but will increase the smoothing, so that jumps like this no longer matter. Each time you increase an interval, the average will increase by the interval step size. This is just a question of getting a data scientist to talk with a dev.

Using the Assioma pedals instead of the trainer is probably not a good idea. Especially if you are using the Assiomaās for the power meter in TR. There is a lag in the power reading, and using the Assiomaās is accentuating that issue. I tried using my Assiomaās with a Kickr bike, and it got ugly, and just āfelt wrongā in ERG mode rides. Reading the output of the Assiomaās on a separate device is fine, but using an outside power meter on any kind of test, to me, seems like not a good idea.
As far as small ring, the big ring will get more spin for each pedal stroke, and will get a physical flywheel spinning faster, which could smooth out your cadence, but could also skew power output slightly. (I had an H2, and always rode big ring, and when I started riding small ring, the trainer felt different, and seemed harder. It was quieter also)
To your question, redo or keep: Iām with those that say to try it for a while and see. I mean, if you are trying to improve, get faster, having, perhaps, an artificially high FTP (and it canāt be that much higher unless you stood for the whole test) will push, or pull, you in the short term. Iād doubt that you are more than a few watts higher than you would have been if you hadnāt stood. You will know soon enough if you are in too deep, and then you have to decide whether to work for the new goal, or dial it back. But donāt think about the numbers, they canāt be off that much, and itās already skewed anyway.
