It's a murky situation. Theoretically, a fan may have bought a HST in January and only attended six home league games and say two away credit.
Remember away credits have also been given for home cup games which adds another complication, so that's a total of eight games in total.
On the other hand, you might have a full season ticket holder who has attended sixteen home league games this season but has no away credits.
One has attended double the amount of games but is below the other in priority. Would it be fair in the situation for the HST to be above the full ST?
It's only hypothetical but that would cause quite a stink...
