Bkool power

Guys I’ve just completed a time trial and came last however I am not sure the effort I am putting in is correlating as the correct wattage etc. Doing average 90rpm in third gear from max (so gear 21 out of 24) and it’s only showing as 110 to 120 watts and I’m going near maximum. I must say I forgot to put my hr strap on. Also the resistance setting is set to 100%. Not sure the Bkool smart pro output is correct to Zwift.

This will be a trainer issue, the trainer broadcasts the power and zwift just uses this value in game.

Do you have anyway of checking the accuracy of the bkool trainer using a separate power meter?

If I remember correctly the bkool trainers don’t need calibrating so that rules that out at least
