Different Power Meters - outdoor vs Indoor

Interested to know how people deal with different power metres and adaptive training. I have an indoor bike with a single sided power metre and dumb trainer that I have used with TR for years and works well. My outside bike is a different set up (cant use it on the dumb trainer). What I am finding with adaptive training is that my outdoor workouts push up my progression levels but when to I come to replicating those level indoors - i struggle. Obviously sticking to just indoor would be the answer but i love TR outdoors as it keeps me honest and focussed. Not sure it really matters… I just adjust the indoor level down… but can get lazy and adjust too much… anyone else have this issue or is it a first world problem of owning too many bikes…

How different are they, and what’s your outdoor setup?
