Can I trust them?

So I was checking hot spot temps and all was well, min hot spot of 89.5 max of 92.5. Then I got to the bottom two tubs. 84 degrees. I'm not sure how bad that is but it was too cool for me. So I raised the thermostat and it's at like 86 now, which is still a little cool IMO. Problem is other tubs are now up to 91.5 to 95. Can I raise the thermostat anymore or no? Can I trust the snakes not to burn themselves? All I know is this is another case of the inconsistensy of flex watt and I cannot wait to switch out to the better THG stuff.

Are you using a probe thermometer or a temp gun? If a probe, just place it in a center tub - they'll be warmer at the top and cooler at the bottom, but it should all be within reasonable ranges.

The probe is in the center, and I used a temp gun to check individual tubs
