Lockpicking help

I was training lockpicking, I got to 76 and switched from the 50 made box to a GM crafted orange box. It says I have no idea how to unlock that, what gives? the guide says to change over at 76 until 95....

You need a 70 made box

The guide says use a 50 box until 76, use a GM box until 95...

Ah I do see in the compendium it says a 70/70 or 12 points detect hidden. The guide I read must be outdated, ty

I have a tinker with 68.4 show real tinkering skill.

I have tinker on 95 if it helps

I was able to do 100/100s at 71.0 with GM detect hidden. If its 5 points to lockpick i dont see how u cant do them at 76.

Check out the Warriors guild in Brit. Under the stairs on the left are like 20 locked boxes. When I reached a point my 50/50 box stopped working I did those until I could do 100/100s
