Some of this math seems suspect. I now have 8 spires/towers. If I collect from them five times in one day ( 8, 11, 2, 5, 8) that's 40 collections. Do that for 3 days and it's exactly 120. Or is my math bad?l
Sorry 4 hour collection so a little harder but still doable: 7, 11, 3, 7, 11.
Of course I have no life and I'm not above shortening that last collection time with one of my hoarded gems. Heh heh
