Baldurs Gate 2 EE Legacy of Bhaal - Thieving question

Those nasty traps in the Mistresses Room in Irenicus' Dungeon lvl 1 - does anyone know exactly how many points in find traps, at a minimum, you need in order to disarm them (even with a lot of tries)? also, how many points minimum in open locks to be able to open every lock in the area?

for traps there is one that requires a disarm skill of 80, and then the highest requires 70 ( quite a few require 70 actually ) i believe that you can have a skill be 5 points lower than required and if you pick at it enough times you will eventually get it opened ( although im not 100% sure if its 5 points lower, or 2 or 3 points, although i would say im fairly certain you can with 5 points lower )
so for open locks, you have to be around 36%+ to open all locks in the first dungeon ( or minsc can break them open if need be )
and for traps you will need at least 75/76% to be able to disarm all the traps in the first dungeon ( or if you don't mind tripping the only trap that is 80, which is one one of the 7 traps in the fancy bedroom - (slanted one "north side" in the group of 3 at the entrance) you could go as low as 65/66% if need be
