I think it's in 80 range for tier five if memory serves. Thanks for your testing, all posts have been noted.Tier 3 appears to start at either 59 or 60 orders. Probably 60, I think I got distracted and failed to mark one run. I'm guessing Tier 4 either starts at 90, or 120 if the number doubles like the titles do. If not, then Tier 5 should be 120 orders. (240 orders for Tier 5 would be a bit excessive)
