Hello.
I have good question mayby it will be help for ppl who wanna start crafting.
So. For example I have Basic Filters bp 1.00 and I wanna unlock Blueprint Comprehension Skill.And here are questions:
How much statistical money I must spend to unlock this skill with 0 in crafting skills and Basic Filters BP QR=1.00 and How much money I’ll lose on skilling (Statistical)
Anyone knows? 
don’t be surprised to loose over 1000 ped 
i would have kept stats, but i had already crafted some before i started crafting again, so that wouldn’t have been anywhere near accurate
You need to atleast get a Qualified professional standing in any of the crafting areas. Thats bare minimum its possible you can get it sooner or a bit later.
Hi level,
BP comp is not hard to unlock. The requirment should be between 1.4~1.6 in any crafting industry. I would suggest that crafting basic filter to 500 manu mech, then change to lvl 3 damper (you can get approximate 150~200 skills in every 10k clicks from lvl 500 to 2k), then you should get BP comp unlock so fast. It only cost you 500peds or less if no hof GL
