Quoted from mwong168:
I checked last night and my personal pit stop record is 3.3s and do the exact same thing every time as described above ramping off the right flipper to the left and shooting for the ramp ASAP.
Just had my best pit stop.
Seems it will be tough to beat that time. Rolled off the right flipper on to the left and quick shot up the ramp. Put a smile on my face!
