Comparing apples to oranges there. Martin's great run of results came after that horrendous run of a couple of wins in 20+ games (I'm sure someone else remembers the exact stats). We had 2 seasons of mostly poor results, then he'd deviate from his 'process' and things would improve, only for him to return to form as soon as the heat was off.
Sheehan took over a side which had lost 7 of the last 9 games, then immediately won 2 and drew 1. After losing the next two, we went on a run of 5 wins out of 8, with only 1 defeat.
TLDR, nothing like Martin's run of wins.
