I recently achieved sub-30 for 40L (29.473) with a really high KPT or KPP of 3.56 (20 finesse), and I can't really go below 3.5 KPT/KPP with a fast time. I am good with finesse, but a 0 finesse run will increase the time by ~3+ seconds. I am trying to learn DAS Preservation, but it is difficult because there is no definite way to learn it.
Later trying 20L, I achieved 12.658 with a KPT/KPP of 3.29 (4 finesse), and realized that I could almost always get much higher PPS this way. I didn't use DAS preservation or pipelining as I don't know how to do it yet.
I was wondering if you guys knew any effective ways to increase PPS consistency, learn DAS preservation, or any general tips.
Thanks in advance
