I reckon 32 - 34pts this season will do it. It's so tight there is 4pts between 10th and 18th.
I'd say you'd get good odds on survival with 32, but it could easily happen, look at the points distribution, it bodes well for a low number. However, this is Albion, we'll stay out of the relegation zone until the final day .... and then score in 90+4 to stay up!
