Non SIB prints will max at 90%
SIB and (L) prints will max at 95%
Understand though that this is misleading, and not anything near the true success rates.
90%/95% is accurate, only in the fact that is counts all returned items, whether it is partial or not. True sale able product returned is more like 40%.
I track all my crafting runs on my site and with 1,089,106.80 PED recorded in values for the year, I am sitting at 41.34% success average for actual product returns.
QR is seperate from the success rate, and is often confused. QR affects it but is not part of success.
Skills and QR determine these %'s As long as you are near the max for that level of print, (level 5 is 7.5 prof I believe) you will be close to maxxing the success rate. Most prints show significant change in success with QR at around 50+ without maxxed skills. IT is a combination of the 2 that is necessary though. Basic skill needs high QR to get max, high skill can use lower QR to get max.
Someone barely into the prof requirement would need a much higher QR print to max success than say someone with 3 times the professional level, who might work with a 1.0 qr print at same success.
QR is a very important factor in what you can craft successfully. As example when I restarted
(no skills from chipping), a rage pants (level 7 bp) 1.0 qr was showing lowest success(20%ish). I purchased a 1.00 qr print, and it went to 86% success, without the skills it enabled me to boost my tailoring skills by a significant margin without major loss.
(High QR is highly undervalued in this game, it should hold alot more value on resale across the board. some prints take literally millions of ped to max out, and sell in the end for +1k, crazy savings)
Skill gains on higher skill required items = very nice skill bonus'. But in order to do so without major loss, you need QR.
I boosted alot of tailoring pretty quick and painless in the first year, so much that my 1.0 level 7 prints were at 70% from 20%.
