Thanks David. The rides with 0.00 against PI are either recovery or Zone 2 rides, so that’s fine. What was confusing me, having thought about it further, was that I was l looking for a PI heading in the summary of all rides but then realised that while the number always reflects the PI rating, the name/ heading could be Threshold, Pyramidal, etc.
Is there a way to get a PI figure for a week, or a month? Thanks, again, for all you put into this great resource.
