Out of curiosity, do you mind sharing how many games you typically send in at a time?
I was planning on doing the same, however, with the lengthy turn times I'm a bit hesitant because at some point WATA would have quite a few of my games and a lot of my money. I probably just need to suck it up and do it, otherwise, it's going to take me years to get stuff graded.
I'd be curious how the different tier priorities come into play on the TATs. For example, at some point I assume they'll have to get a turbo order done before a speedrun.
