Based on PPG (and not including caretakers who were in charge for 1 or 2 games and lost it/both) Maynard is currently the 2nd worst of all time on 0.50.

For worse than Maynard you have to go back precisely 90 years (1934) to a guy called Charlie Jones whose PPG is 0.41 with a record of Pld:17 W:1 D:4 L:12. However he was up against the likes of West Ham, Fword, Sheff U and Newcastle United in tier 2. At 4th tier level Maynard is currently the worst of all time.
