Low pop era server honor calculation

Honorspy seems to be screwing up a lot. I played 1 game of av yesterday and got 25k honor for it when the daily calculations came in which pushed me way over the established brackets. The guild is saying there is a max of 15k honor per av and its making it look like i intentionally broke the bracket. just trying to understand how 99 hks in 1 av ended up giving 25k honor instead of the 6k honorspy showed it giving.
