btw. I forgot i made my activity private. it should be public now
it's up to you how you handle it; some devices are much more sensitive to temp swings than others.

specifically: depends on the meter.
one data point: the physical orientation of the strain gauges in SRM is such that changes in material properties due to heat tend to cancel out, so temp swings have minimal to no impact. it is pretty normal for me to take a bike from an uninsulated garage in the winter (temps <=20F) and ride indoors (70F) with no change. also, a normal summer day has overnight temps of 45, 50F and can be 95-100F in direct sunlight.
other meters can and do vary more when temp fluctuates.

maybe just do this for an 'important' workout? for example, if you're doing a 20' test, warm-up, then check ZO before and after that interval.
for a tempo session, who cares?
