They should really stop pushing weekenders into buying PMs and into thinking that PMs will somehow enable them to do something that requires genetic blessing. No PM is gonna overcome a genetic deficit.
For me it's quite important that my bike PM correlates well with my indoor trainer PM. Fortunately they are always within a couple of percent and both are consistent. They could both be reading power in units of chicken-power for all I care. I find both PMs massively useful for both training and events and you would probably class me as a "weekender". The only bike I don't have a PM on is my mtb, as I don't really think it would be a lot of use for the casual trail riding I do on it. But on my road bike a PM really helps me to pace long Sportives and mountain climbs etc. I'm not sure anyone thinks a PM will enable them to do something that requires "genetic blessing" as you put it!
