I recently did the ramp test with a new FTP result of 225 w. This was around 3 weeks ago and since I have been following SSB1 LV. I have just completed a 70 mile sportive on Saturday in 4:30 with a NP of 202 w.
Too many factors to know for sure. What was your average power? Most people can put out more power outside, so I wouldn’t say your numbers are abnormal, but I’m sure you have already experienced some gains since your ramp test. I would just wait and retest after this block unless your workouts feel unbearably easy.
Possibly, but with a big caveat. I say “possibly” because this implies you did 4.5 hours at 0.9 IF, which is pretty heroic. I’m thrilled if I can do a 4 hr event at 0.84 or so.
That said, if you’re going off different power meters, or have a PM on the bike outdoors but use a trainer’s power data indoors, then all bets are off.
This is about right - but I’d add that if the 3 weeks of SSB is the first proper training you’ve done in a long time, or even ever, it’s plausible that you might have already had a very quick bump in your FTP.
