I got this freaking wonderful Mine Glitch on one attempt. I were down at 15s ahead after Himalayas (2nd level) but lost some towards Vesuvius (still had 6s ahead at Dracula). Unfortunately the run was ruined by two bat patterns.
Even without this kind of a Mine Glitch, I know sub 31 IGT is possible.
