CT clamp calibrate calibration issues.

The problem

I thought I got it squared away w a space heater and a watt meter that shows amps. The watt meter is plugged in along w the CT clamp around the same power wire. Should be the same rating. I can fix esphome with this Calc. 0.037 -> 11.6

That then showed correct in Esphome at about 11.6amps. Then I tried my laptop charger, it's off by double, much closer than before, but double. Esphome shows like 0.212A and watt meter shows 0.35.

Do I put in both these under the linear Calc? Or what happens if I get rid of all of it? How did I fix one thing but it shows so off when trying on a second device?

This will eventually go on a water heater line in breaker box so trying to get this right before installing it.
