EDIT: I now think the "predicted RFL score" feature that I tried to include was very incorrect, and so it has been removed . Was excited for that one, but I think the only way to estimate it is by running several simulations of the sets. Perhaps a project for the future. The time to find a given rune from each area and the subsequent comparisons should still be good though! After some helpful suggestions (mainly from @ffs , thanks!) in my first post HERE, I have greatly beefed up my runefinding calculator. It now includes runefinding data for what I considered the relevant round 3 areas: pits (this would also work for tunnels/ mausoleum), chaos sanctuary, and arcane sanctuary. I will include more detail about the new features below, but here is the link: Runefinding Calculator v2 (google sheets, click to access) For people NOT willing to record videos and count monsters: The first page should still be pretty much the same, and the instructions on the right will describe how to use the sheet. The Round 3 data should be ignored, as it is highly dependent on decent inputs that have to be derived from recording video and counting or another method of counting monsters, such as the longer-term charm and rune counting method that @Gripphon plans to use. For people willing to record videos and count monsters: The "OTHER AREAS" page is where the round 3 inputs will be entered. Bosspacks should be nearly irrelevant, and feel free to leave them as zero. I wanted to include them for use cases such as someone running a p1 tunnels sorc wanting to see how long it should take them to find a rune. In a case like that (low psetting, many bosses) the bosses do become relevant. I also included the option to kill or not kill all the arcane and chaos superuniques, as well as diablo. This also makes very little difference, but I liked it for completeness's sake. Made the new version very, let's say "interesting" to calc . Let me know if anything is behaving strangely. Always tough to keep from simple formula errors in a sheet this big. But hope some people enjoy it, and of course let me know of any issues or suggestions! Good luck to everyone during RFL!
