Great…
However, since this is for a test to see power differences, you do not need to be doing a full workout (though there’s no harm in that )
If for me, for testing purposes. a quick few min rides is all that’s needed actually.
It can be as simple as creating a 5min ride at say 230w and then just seeing the power differences (if any)
Per MedTechCD, Your Garmin will
- Control the trainer by sending 230w power target
- Power Reading on your Garmin Headunit (prioritising the “real” power meter - assiomas) will show 230w +/- 10w or such if all is good.
- the +/- is because the assiomas are supposedly “highly accurate” w/ their IAV and such, any small changes in how you pedal / pedaling style / power etc will cause some differences, but +/- 10w, that’s to be expected
- if you see values like 260w (+30w) or 200w (-30w) then you know that there’s an offset.
Also, your trainer is a Kickr Snap which is a Wheels On trainer. My past experience w/ a (dumb) wheels on trainer is - tire slippage, not enough or too much tension, all of these can create differences in power at every cycle stroke.
