Turbo Trainer Advice

The SRM reckons I averaged 240 watts for the 10 minute warmup, the PowerCal reckons 194 watts.

The SRM gives an average of 220 watts for the 45 minutes, the PowerCal says 191 watts.

Anyway, it's possible that my fairly constant HR isn't ideal for the algorithm- I simply don't have enough data yet.

I'll go out dorked to the max at the weekend and see how the two power devices track each other when on the road.

Thats kinda disapointing. I was expecting the 45 min workout to be more accurate on the PowerCal.

Also I thought HR data was collected at the same time as power with the powercal belt. Why did you need the Garmin belt?

I'm quickly coming to the conclusion that I'm going to have to compare indoor, and outdoor performance separatly. Which is no big shock* I *guess. But with only TrainerRoad to calculate turbo training power, PowerCal to guesstimate road performance, and no absolute meter. They just dont seem comparible.

Still for the monies they seem like two nice training tools.
