using
https://eisencalc.com/ for ruin abilities until ps updates (i did that manually before :skull:)
using relaxed nature doesnt make much sense to me, but its not really important. also facade doesnt do anything afaik, against wisp users burned payback or earthquake will still do more.
anyways, here's the spread i came up with using adaband iron hands CC and timid specs iron bundle hydro pump as the benchmarks (and how i did it).
I started with 252 hp since we have 2 benchmarks, and added evs into defense and special defense until it tanked both moves. This ends ups costing more than 508 evs btw.
+1 252 SpA Ruin Iron Bundle Hydro Pump vs. 248 HP / 64 SpD Ting-Lu: 434-512 (84.6 - 99.8%) -- guaranteed 2HKO (64.00% chance to 2HKO after accuracy)
+1 252+ Atk Iron Hands Close Combat vs. 248 HP / 204+ Def Ting-Lu: 434-512 (84.6 - 99.8%) -- guaranteed 2HKO
since both attacks are super effective (and there arent certain multipliers messing with things) the optimal hp will always be an odd number.
so to find the optimal spread im going to lower the hp by 2 and add defense and spd to tank both hits again, and repeat. Sometimes this wont save any evs at all, and sometimes it will save 24 evs. Just go until its clearly not saving evs anymore. I recommend using 2 calc tabs and a ps tab to store the most optimized spread.
Unfortunately, ting-lu cannot fully tank both of these attacks, so you could bulk one of them to only ko with a max roll, but im not doing that lol.
