Question Did I mess up my Trainer Road ramp test?

Hi there,
Quick background: I’m a NorCal Cat 3 road racer who’s consistently in the top 10 (but not quite top 5). I was a competitive runner and mtb racer prior to being a roadie.
Issue: I’m new to Trainer Road and just got started. I didn’t start SSB MV1 until today. However, I took a ramp test three days prior to officially starting (out of curiosity) and had a w/kg result of 4.02, with FTP of 241. When I took the first ramp test it was early in the morning and I hadn’t eaten anything. Today, I took the first official ramp test of SSB MV1 after work and was quite full of food/energy. My w/kg for this ramp test was 4.28, with FTP of 256. I made sure to calibrate my Quarq Dzero power meter before the test. I noticed that by the last minute I was holding significantly lower than the required watts but still held on as hard as I could.
Question: Does food/energy make THAT big of a difference or did I mess up the result by holding low-ish watts for the last minute? Also, if I go with the higher FTP, is there a risk of over training? And if I go with the lower FTP, is there a risk of under training? It’s a 15 watt difference in FTP’s but I figure that could totally skew my training zones.
To be completely honest, 4.02 sounds pretty consistent with where I think I am (top tier of Cat 3), especially in December. 4.28 would be amazing but I’m not confident that that is where I am.
Any insight would be super helpful for this TR newbie.
Thank you in advance!appvalley tutuapp tweakbox

I'm no expert, but the recommendations I've seen are better under-estimate your FTP than over-estimate it. You'll know soon enough if it's over, some workouts will be very, very hard to complete if you are.

As Red Flanders said, yes it's better to slightly underestimate your FTP than than go over. FTP is rarely a static thing anyway, so a good program will have you test it again further down the track as confirmation of the training you're doing. If it's definitely too low you will feel it after a week or so, but 15 Watts isn't massive as the starting point.

Blood sugar can make a bit of a difference, along with how warmed you are and cumulative fatigue. It's usually recommended to test when fresh and recovered, and after your usual pre training meal/snack
