Im not shure about anyone else but when I started picking I was putting a decent amount of pressure on the wrench and pushing the pins quite far up.
At the time I thought it was the correct way to pick but the other night while I was messing around I imagined to myself the scale the I was working on.
And so I tried to put less tension on my wrench and only slightly lifted the pins.
Within a couple picks I had unlocked a lock that would usually take me 10mins to pick.
This is usually overlooked in lockpicking tutorials as it is hard to describe to someone the amount of force to use when picking a lock.
So my advice is to visualise the scale that you are working on - pins are only a couple mm long.
Use feather like tension and lift pins with feather like power.
