They have Hybrid wax seals too. It is like the foam rubber and wax combo so if the toilet moves at some point the secondary seal kicks in and fills the tiny gap the wax left.
Also extreme plunging takes it toll on a seal. Take it easy.
Experienced this in my townhouse...the toilet in the powder room on the first floor was rocking due the concrete not being level. Builder sent plumber out who lifted the toilet slightly to shim it and tightened it down. I told the guy that I was no expert but isn't there going to be a problem with the wax ring now? He assured me there wouldn't but two days later I noticed seepage when flushing so the same guy had to come out to pull the toilet and put in a new wax ring.
