I love all these 30% numbers and such people give when in reality its more more 5-7% at that quality

it really isnt that big of a chance until you get way higher up and even then its not great

Reality is that chance of +1 caps at about 200 quality, and more quality only raises the odds of +2 or +3. Each of the chances are sigmoidal curves that start their inflections at different qualities and cap at different absolute rates. That's why most of your results at 500+ quality are still NQ.

basically it right here. From my experience, 1-99Q chance for +1, 100-199 chance for +1-2, 200+ quality chance for +1-3 As ive never made a +2 item with anything less than 100, never made a +3 with less than 200, but have made them with the stated values. As to the % chance it increases as you get on your knees and pray as you hit touch-up
