I'm curious if anyone ever looked at this information, but is there any sort of vague range of how many blocks (not including water, lava, air) are in a Terraria world, especially a small one? I ask only because I am working a Hallowed world, and I'm curious to know how much of a difference my carving out of un-Hallowable blocks counts for. For instance, when I carve out 50,000 blocks of mud, is that 00.5% of a world? 00.1%? I'm pretty committed to finishing this achievement (at least this one, can't say the same for Corruptible as well) by myself, but I'd like to be able to estimate how many more blocks I'd need to remove to finish. For every 10% of blocks I carve out, it increases my Hallow% by about 10 percent of itself comparitively (30% Hallow would become 33%ish), so I know I need a bit more than 25% of an entire world's worth to get my Hallow from 39% to 51%. And thats a heck of a lot of blocks, that much I know.
