I just wanted to create this thread to compare individual ante times. For those who want to look into their stopwatch/speedrun timer and post times, your contribution is appreciated - from there we can share time-saving methods, common cards and strats, etc.
I'll go first, using my 5:16 RS Skipless run: Ante 1: 52.0s (PR 41.1s) Ante 2: 48.4s (PR 36.1s) Ante 3: 1'01.1" (PR 40.9s) Ante 4: 1'07.6" (PR 55.7s) Ante 5: 1'11.4: (PR 38.5s) Round 16: 16.6s (PR 13.9s) Sum of segment PRs: 3'46.2"
Obviously these will be much faster in the other categories, but I think that RS has actual strategy (as opposed to just speed in SS) and is therefore more worthy of discussion here.
Here are the splits from my 5:12. My sum of best segments is a 4:42. As for strategies, honestly the biggest difference I've thought of is using high card instead of pair, which could save time due to being easier and faster to play, with the downside of scoring fewer points. It's what the current SS skipless record uses as well.
