Guild Wars 2

I have a few questions about this:
1) what can be salvaged that has a chance to return an inscription? All I’ve read so far indicate ‘any weapon that wasn’t crafted and has stats that the inscription to make those stats can’t be crafted’. I’ve tried salvaging a few exotics. 10 of each. King’s Remembrance gave 0 Magi’s inscriptions, Guild Defender gave 0 Soldier’s inscriptions, Atlatl gave 7 Shaman’s inscriptions. All 3 of these inscriptions can not be crafted, yet not all 3 were obtainable via salvaging. What other criteria is there?
for those who say I was just unlucky, I’ve calculated the odds of getting 0 inscriptions from 20 salvages, assuming 60% chance of success: 0.00000010995% = 1 in 90,949,470

2) what is the chance of recovering an inscription? a few people have some small sample sizes that say about 60-80%. anyone with over 100 salvages?

3) is there any difference in chances between Master Salvage Kit and Black Lion Salvage Kit?

Where did you get a 60% chance of success number for salvaging the inscription? I was under the impression it was a much lower percentage (like less than 1%).

well, other people I’ve read have reported 66%, 70%, 75%. some have reported 0%, but those may be what I’m experiencing (where some items give them and some don’t).
Myself, I’ve salvaged 10 Atlatl and got 7 inscriptions. I consider that proof that the rate is close to 70% – if the inscription can drop. Due to the low sample size, this can probably be up to like 20 off, so 50%-90% is my expected range. I figured 60% would be a safe lower guess.
If it turns out to be 70%, 20 failures in a row would be a 1 in 28,679,719,907 chance (if 1 salvage per second, this would happen once every 908 years). 80% would be 1 in 95,367,431,640,625. (once every 3 million years). 50% would be 1 in 1,048,576 (once every 12 days)

I made a fun math spreadsheet
if you get 7 inscriptions from 10 salvages, these are the chances of that happening at these percent chance to get an inscription:
40% chance of inscription = 4.2% chance of getting 7 out of 10
50% chance of inscription = 11.7% chance of getting 7 out of 10
60% chance of inscription = 21.5% chance of getting 7 out of 10
70% chance of inscription = 26.7% chance of getting 7 out of 10
80% chance of inscription = 20.1% chance of getting 7 out of 10
90% chance of inscription = 5.7% chance of getting 7 out of 10
which is why I believe 50-90% is the rough ballpark for inscription returns.

anyone have larger sample sizes or know if Master vs. BLSK makes a difference?

so… I made progress. Results:
1) A few items that I would expect to drop inscriptions but didn’t: Guild Defender (10 tries with MSK, 5 tries with BLSK), King’s Remembrance (15 tries with MSK), The Ugly Stick (5 tries with MSK), Poyaqui’s Noggin (5 tries with MSK), Occultist Flame (5 tries with MSK), Scepter of the Highborn (5 tries with MSK), Defiant Blaze (5 tries with MSK), Faithful (5 tries with MSK), Monsoon (5 tries with MSK), Pearl crafted items, Quaggan crafted items. It seemed to just be random in most cases.
I haven’t checked all of them, but I have checked the majority of the others. Anyone want to check a few for me? (especially Azureflame, Feathers of Dwayna, Jormag’s Breath, Melandru’s Gaze, Eye of Rodgort, Glint’s Scale, Lidless Eye, Squeedily Spooch, Titans’ Vengance, and Arachnophobia – yes, these are all Forge items that use Eldritch Scrolls to make for science anyone? yes? yes?).
The odds of not getting one from 5 MSK salvages at 45% return would be 5.03% – certainly within the realm of possible, but also not very likely.
2 & 3) out of the things I had previously got inscriptions from, I got 91 inscriptions out of 200 salvages with MSK (45.5%). with a similar group of items, I got 33 inscriptions out of 50 salvages with BLSK (66%). It’s worth noting that you get 0.9 ectos from MSK and 1.25 for BLSK: kitten * 1.25 / 0.9 = 63.2%, which is close to 66%. Accounting for likelihood that these are a bit off, that could be the same proportions.

4) Soldier’s, Magi’s, Rabid, Shaman’s, Dire, Cavalier’s.
Every dungeon except CoF exotic weapons with one or more of these stats
