mmk, the outer four segments of track would each be 3000 blocks long times the four segments which make up a square. That's 12000 blocks long.
12000 / 11(coal ps) = 1090 protection stones required, and this is just the outer track.
Now for the inner track:
1000 X 4 = 4000 / 11 = 364
1090 + 364 = 1454 coal protection stones.
1454 X 1500 = 2,181,000
While I am totally capable of reaching that target amount (iron farm), I am still stuck with the issue of the numerous coal protection stones. Sure it's expensive, and I could earn the money for them, but the true issue at hand is the fact that now the server would have close to 1500 more protected regions to watch over, and that means the database would become larger to hold the data for the 1500 more regions and their flags, the server would have to loop through each region per tick, and more RAM would be used. I mean, we're talking 1500 more regions in the database, loaded in memory, etc. It's just a project that would need protection, but only of the tracks. 8 regions total would do it.
