2. Power at 120 beats per minute, this is approximately my first ventilatory VT1 point. For me, this is the most important metric.
10% off in power has a big effect on TSS and TSB because it is based on IF squared. 0.8 vs 0.7IF is about 15 TSS points per hour. That is huge.
yes, huge. for me 10% is the difference between a fairly casual workout ride and a nearly-best-ever effort. 200w average vs 220w average over two hours is a huge difference.
maybe i should get power pedals for the creo, they’d probably be a closer match. but a pain.
