5m performance seems to be wrong

[bmacher]

Hi, in my recent ride my FTP was increased because I had 5m:30s @316W. However, my 5m performance was somehow only 311W. Is their any explanation I’m missing? I mean it should be at least 316W but most likely at little higher.

It’s surprising but it is actually possible and almost surely correct
Look for explanation in this thread:

FTP curve correct?

On the FTP curve I see that my 19 minute max is 246 [image] 20 minute max is 248 [image] and 21 minute max is 250 [image] my 19 and 20 min max should also be at least 250 so I think something is wrong in the curve. a similar situation exists on the FTP curve at 25 minutes → 245 [image] and at 28 minutes → 247 [image] also at 95 seconds → 386 [image] and at 70-90 seconds → 385 [image]

hat makes perfect sense, thank you. I did a sprint at the end of the climb that was 5m:42s, so I have a peak for the 5m:30s average, however my 5m window was smaller.
