TPMS question

So how accurate is the TPMS system?
Just used a Slime 0-120psi dually bourdon tube gauge to check and adjust tire pressure.
backs are set to 65 and front to 62psi.
The TPMS shows rear at 64, 61 and fronts at 62, 64

Is a pound or two acceptable? I used to use the Slime digital but in this heat never know when the battery dies.
Don't want to overthink this but trying to get acclimated to the norm for the 6.2 vehicle parameters and have a long way to go.
Thanks...

The gauge and the TPMS will both have a % of error. Just have to decide which is closest to being correct.

But no, one or two pounds will not make a enough of a difference to go crazy over.

Thanks.
Yeah the rears both read 64psi via the slime gauge yet TPMS readout was 3 pound delta.
So looks like I'll use it as a monitor for anomalies while towing or long road trip and not get OCD. heh...
