That is a non starter and I will do something else.
The other issue for me is how to know when you have reached that CD target while riding. If there was a Garmin IQ app one could use to calculate it as you ride during an interval or set of intervals that would be something I could execute, otherwise how would you know? Seems it's a fairly complicated target to predict performance vs while riding a trainer.
