Cap Math

Someone with JUST a high skill has the same chance as someone with a lower skill that threw AA's at it. Those "caps" are set so that a 300 skill does not see the caps. At a plain skill, your chance is the same as the cap (ok so now people can figure the caps) At least this is true for the cultural. I have not checked the OOW augments. It is not true for some of the caps I put in (caps on items since DoD), but those are in for lore nearly as much as for limitations...

So for many items, the cap is set to the success rate expected at 300 skill with no AA. I also assume it is set to the success rate at a skill of 300 and no gear with a tradeskil mod.

Thank you for that information Ngreth.

I don't believe that quite to be the case. If it is, you get the following numbers for GM items:

Armband, 95% (114.5% calculated, capped at 95%)
Boots/Gloves/Helm, 95% (101%)
Sleeves, 75.5%
Cuirass/Greaves, 62%

Now, the Cuirass/Greaves, Sleeves, and Armbands are fairly close to what people have estimated (60%, 70%, and 90%). The Boots/Gloves/Helm have been estimated at 80%...so 95% would seem to be quite a bit off.

One other related question:

GM armor has success caps. It ALSO has a bonus chance of skill-up. So, do all items with success caps have a bonus chance to skill-up? (OOW augs, for e.g.)

"All" is not correct.

"most" is.

(the OOW augs, and DoN armor)

Heh. I'll bet I can tell you the reason for the discrepancy. =) Most players don't think of the minimum fail rates on items like Dragon Mayo or the Jeweler's Eyeglass as fails per se. While the mechanic is the same as the minimum fails on GM armor, you get everything back when failing the former. Hence, there's no loss, so although you may fail the combine, you lose nothing. (At least nothing of value.) Consequently, players don't think of those as fails at all, just a clever game mechanic.

But the Sporali skin is an example of an artificially high fail rate (cap) with no skill bonus. But then, the skins are not particularly rare either.

So there are a few But htey have a lore around them also.

Doesn't the 250+5% mod+Mastery 3 match better? eg for GM boots, triv 334 works out to 81.5% success rate...

Sleeves at 368 vs 250+5%+M3 works out at 68.75%

Greaves/Cuirass at 386 vs 250+5%+M3 works out at 62%

-- which would seem to match the reported success rates better than 300+5%+noAA?
