I guess that giving both sets of figures *could* allow the club to prioritise a match or two to non-STH ahead of STH with few points, although I can't see it happening.
I'm sure I'm being dumb here, but if you are a STH, surely it's just necessary to tell you your STH points, as the member points are an irrelevance if tickets are going to be released on a tiered basis to STH first, and then members later?
