I don’t get why I have a new Avg Pwr 20m best which is less than a 22m+ interval on the same ride?

related?

There is definitely something wrong. Probably the code is not choosing the best possible interval to calculate max power. Had similar ride with 1h max power discrepancy.

Imagine that you do 5 min at 200 watts, then 5 min at 100 watts, then 5 min at 200 watts.

Best power for 5 min: 200 w

for 10 min: 150 w

for 15 min: 166.67 w.

The best power figures are for what you *actually* did, Steve; you are thinking about what you *could* do.

Have found the answer in another topic. The higher wattage is without zeros (when you stop pedalling for a second or your trainer disconnects for a while). To see real avg power you have to check the “real avg pwr” ticker in fields menu below the graphs.Check if real avg power gives you 328w.

Well spotted, that put the 22m interval at 326w so now believable compared to the 328m for 20m best. Thanks for posting

I disagree, I understand the numbers you posted re 5,10,15 mins etc but the case I mention the 22m interval was more watts than the 20min best which should not be possible for the same time period as the 20m was **within** the 22m. For example if I do one 10 minute interval and my 10m avg pwr is 300w then my best 5 min **within** that 10m must be equal to or greater than 300w.

Lukasz seems to have found the answer though.

Those power records are taken from your configured “Best Efforts”. So you have 20m set but not 22. I have an outstanding todo list item to generalise this for any time you push out the power curve.

With regards to 20m having lower power than 22m this is definitely possible (as @Michael_Webber says). Consider a 20m effort with 1m on either side at much higher power. The 22m effort will have higher avg power than the 20m effort because the 20m effort can only include one of the 1m higher power bits.

It took me just 2 minutes to figure out the answer without having to dig into anything … but I was amused.

Good for you

It took me a while to work it out, Steve [certainly longer than 2 minutes!], so no worries.

Brilliant!
