No hate or flame from me, lol.
The vent rings i've tried on ender and monoprice personally, and the ones i've messed with on prusa all send a lot of air to the nozzle.
The cooling should happen just after the fresh layer touches so I designed this to only use the waste air from hot-end fan for nozzle-area.
Leaving the fresh cool air to hit as the nozzle moves away. Has your printer responded the same each print? The diagnostic side of me
is most curious in trying to help.
