What front pin? Lmao, haven't seen that pin in yonks. When I did see it, didn't have decent spin clubs so I'm afraid I can't explain it using past experience, but I have a theory...
With the pin being so much easier, the only chance I'd get to see it is in practice mode & easy pins, so it'd be on the VF greens. VF greens are slower, so it'd be less likely to roll back.
However, this is useless info if the mystery happens in a ranked round if you're a TM or Legend.
