Q: What are masterwork rolls?
A: Most legendary weapons are capable of being Masterworked. The masterwork system is a way for you to upgrade your favorite weapons to their maximum potential.
Q: What does it take to upgrade a weapon to a masterwork?
A: Upgrading your weapons, in broad terms, takes a small amount of glimmer, legendary shards, and, most importantly, Enhancement Cores.
Depending on what Tier your weapon is at, the requirements to raise it to the next tier increase the closer the weapon is to being fully masterworked (Tier 10).
Q: What benefits do I get for masterworking a weapon?
A: Each tier that you increase your weapon will grant a small buff to a single stat, chosen randomly when the item drops.
Beyond that, at Tier 5 you gain access to a kill tracker. At Tier 10, your multi-kills will generate orbs of light.
Q: So what are these "masterwork roll" stats?
A: These are the possible stats that upgrading your weapon will grant a bonus to. Depending on what tier you are at, you can grant anywhere from 1-10 additional points in any of the stats listed to your weapon.
Q: Any catch with this?
A: The Bungie API currently says that all weapons can potentially roll with all stats as their masterwork stat. This obviously isn't accurate, as Blast Radius isn't applicable to, say, Auto Rifles.
The list you see on this page is trimmed to only show stats that actually appear on the weapon. However, it is possible that Bungie has additional logic behind the scenes that further filters these
possibilities to, for example, prevent certain items from being able to have an Impact masterwork. Until Bungie modifies the API files to 100% accurately display which masterwork stats are possible on
each item, take what you see here with a pinch of salt.
{My math for Triple Tap, 16-3+1=14, 14-3+1=12, 12-3+1=10, 10-3+1=8, 8-3+1=6, 6-3+1=4, 4-3+1=2 that's a total of +7, which is 16+7=23}
{My math for Fourth Time's the Charm, 16-4+2=14, 14-4+2=12, 12-4+2=10, 10-4+2=8, 8-4+2=6, 6-4+2=4, 4-4+2=2} that's a total of +14 to the original 16 which is 30 total.
KEEP IN MIND YOU HAVE TO HIT HEADSHOTS FOR THESE NUIMBERS TO BE TRUE!
So yeah I think he fucked up the math.
Anyways, the pewk itsewf is wike a weiwd vewsion of Twipwe Tap ow Fouwth Time - instead of giving you onye/two fwee buwwets fow evewy thwee/fouw consecutive headshots, it wefunds up t-to hawf (fow Pwimawies; Speciaws instead get ~40%) youw successfuw hits once the magazinye wuns ÚwÚ out, which c-can twiggew muwtipwe times without wewoading. Fow exampwe, a 16-shot Vision of Confwuence can give up t-to 8 wounds, then 4 wounds, then 2, then 1, effectivewy wetting you shoot it 31 times without wewoading if you don't miss once; compawativewy, Twipwe Tap w-wouwd wet you shoot 20-21 times and Fouwth Time w-wouwd wet you shoot 2-24 times on the same weapon (assuming I didn't fuck up that math, and nyot that Vision of Confwuence can have eithew). On a Pwimawy weapon at weast, this is both bettew and mowe fowgiving than its othew countewpawts, as Wewind Wounds d-doesn't wequiwe headshots (though you shouwd stiww aim fow those). So yeah, I say it's good.

That aside, I can agree to the points you made.
Although, seeing this on a trace rifle has me excited to see it's usage.
