?? where are you getting that equation from ??

Linked to SNR, maybe, but that's not the same thing as max TX power unless you're standing right at the edge of the cell.

Not parent, just asking the same question.

There's a log here, so it doesn't even seem linear to SNR.

Would SNR increase linearly to TX power?

I don't know.
