Thanks for posting! I'm relatively new to ML and haven't seriously made a run at a progressive island yet, but Stake is very tempting so I want to understand the algorithms and costs better. Before deciding to push for it or not, can you confirm I'm understanding this all correctly.
If one's goal was to win Stake out of this progressive island (not ranked), if one was perfectly efficient in their collections, it would take 22.2 days (adding up the red hours in your image). Using the calculated strategy, it becomes theoretically possible to get Stake in 12.7 days utilizing 1,141 gems (assuming there's bonus island time that gives us the "~13 days"). Given collecting is unlikely to be perfectly timed and efficient, it's more likely to cost someone 1200-1500 gems.
So am I correct that if one wants Stake through this island, they should be budgeting 1200-1500 gems and efficiently collecting, especially if we get 'bonus island' time?
