They are very loosely a 0-100% indicator that shows how close to a minimum or maximum roll for that stat you are. The rating of a weapon is a summed value of those stat bars, properties (10/15/20/25 each) and traits (25/35/45/55 each). so higher rating = more points distributed to the bars, but that also means that a low damage roll higher rated weapon could do less damage than a high damage roll, lower rated weapon. They are modifiers ontop of a base stat, some wont have all the variables listed actually be changed, it depends on the weapon but this would be a loose baseline. Stats cant go past 100% if multiple bars affect the same stat (like defence and mobility affecting dodge)

"For the rating it is based on :
o Mostly your character level
o A bit on your trait/perks amount (rarity)
o A bit on your trait/perks rank, so the quality"
