Given the immediate pre-season, the game at Batley and how it must have felt that, at least a little bit, like things were falling apart that is indeed an impressive slope for you guys.
The 2005 stint in SL is there, it's the lower one sticking out at the bottom towards the right. FWIW, very, very far from the worst run in SL.
That honour belongs to the hill people of Halifax in 2003. Won their first game against London, lost all the rest. You can see them basically
rlflatline in the HFX plotrl. Similar story for London in 2014, where
rlthey too only won a single gamerl. Oddly, that was against Leeds at Headingley and happened mid-season. As bad a performance within one season as that by Halifax in their crisis year but punctuated with a win.
Anyway, not had chance to split this up for you yet. In the meantime, here's a table showing percentage of all available points won in all games played. Should make it somewhat easier to cross reference against the plot.
This will be much easier to do when it's dynamic and you can pick which teams and years for yourselves. It almost works, but probably won't be available to play with until next season (cos there's a whole bunch of other goodies coming at the same time).
