Getting it down to 8 (as much $ as I was willing to spend) took weeks of intensive taste testing.
IMHO, that's how it should be. You advanced 4 out of 8, right? I entered 4, advanced 2. But I'm also not crazy enough to just enter as many beers as possible to "increase my chances". If you have 15 EXCELLENT beers, then great - enter them. But I cannot tell you how many entrant envelops I stuffed from our regional that had 12-15 entries with not only none advancing, but also some pretty low scores for most of the beers (mid 20s). I can't imagine paying $15 per entry on a beer I didn't think was world class.
Even if the cap was 5-10, I'd still maybe enter 4-5 beers a year.
Okay, soap box rant over. Carry on!
