But why does that matter if your hub based powermeter reads 3% lower then your crank based powermeter? As long as they are both reading consistently the same numbers it doesn't matter if one is reading the 3% drivetrain loss.
I'm looking at the bigger picture/equation...from an engineering point of view, you give your competition that 3% advantage, whether it be a reduction/increase in drag, downforce, top end power, mechanical grip, or anything for that matter, they will use it to their advantage and beat you with it...as the saying goes on this forum, hence it's name Weight Weenies, "every ounce counts". To a weight weenie, do you think a gram/ounce of weight here and there on their bike is insignificant? You take whatever advantage you can get, small or big, and use it to your advantage to beat your opponents. It's attention to details that will set you apart. That's why that 3% matters...Let's say you and I make 300 watts of power, you at the pedals and me at the hub, what's your conclusion? Will that 3% advantage I have matter to you? Maybe not, but it all depends on what perspective you are coming from...my 1 cent worth....
Nevertheless, I will say that it is the cleanest looking power meter solution I've seen...
Anyway, I think we might be going a bit off topic here...apologies to the thread starter...
