I don't have Armada Hauberk (probably won't for a while with my luck, only 1/11 Fafnirs dropped Sweet Tea) so my goal is to get Radiant Mail for this purpose.
I have a bit of a "dirty" 6-hit Restraint down build using the normal +1 body and NQ head (it will leave me with 99 tp if the second hit of Ukko's Fury missed AND the first hit didn't double attack)
13 x 1.3 (30 store tp from trait and gear) = 16.9 x5 = 84.5 TP. So I need 16.5 TP from a WS.
I'll say 15.5 assuming the WS hit twice (or the first hit double attacked). 15.5/13 = 1.192 (20 store TP). SAM 45 Job Trait + Rajas Ring alone will cover that.
Frankly though, I'm always using Save TP atmacite in Voidwatch, and on anything else I'm pretty much always being hit, ensuring that I get 100tp in my normal cycle regardless of my luck with WS accuracy.. Someone has suggested fulltiming Rancor Collar though I haven't tried this yet, and Gamayun won't put out for the earring.
My goal with this set was to achieve higher fSTR and attack during TP while still keeping my hit build and haste. I bought the +1 body instead of +1 head because the head would put me over the haste cap pointlessly and add 2 attack, while the body would add 1 more STR and attack, which can double as a piece for my SAM.
