I'll work on assembling a program to do the parsing; I have most of the code in place, it's just a matter of grafting an appropriate UI onto it.
In terms of proc rate determination: for those of you that wish to take data, the general rules of thumb are as follows:
1) unequip all items that proc haste effects - Thundering Skyfire Diamond, Mongoose, Dragonspine Trophy, etc. - with the (possible) exception of the proc you're testing.
2) only equip a single weapon; while two-weapon testing is sometime useful, it is only circumstantially possible; in general, testing with one weapon is safer.
3) If you have haste rating items equipped, record how much and report this value with the data.
For information on the interaction between haste and PPM effects, I would refer you to the following thread:
Proc Per Minute Mechanics & Haste
The information found there, while not 100% conclusive, is reasonably convincing that PPM effects on noninstant attacks is based on current weapon speed, and on instant attacks it is based on base weapon speed.
In terms of weapon speed: many rogue will find either 2.6 or 2.7 to be convenient to test, and either 1.4 or 1.5 as well; relatively fewer will find both to be convenient. Warriors/shaman, I can't speak for. However, we don't need to standardize across all tests; so long as data for any particular proc is collected for the same speeds, we can change between procs. So, for instance, Mongoose testing has started at 1.4 and 2.7; but we could still do, say, 2.6 and 1.5 for Executioner.
Additionally, some procs were pinned down in some detail in the Mechanics Testing Thread, which I can't find anymore but do remember a few results for:
1) Rod of the Sun King is ~4.5% proc rate, hence hypothesized as 1 PPM. Would need more testing to determine if it's actually 4.5% or if it's 1 PPM, as they perform differently with haste.
2) Dragonspine Trophy is 1 PPM with a 20 second cooldown
3) Tsunami Talisman is 10% on crits with a 45 second hidden cooldown.
4) Band of the Eternal Champion is 1 PPM with a 60 second hidden cooldown.
5) Madness of the Betrayer is 1 PPM with no internal cooldown.
6) Warp Spring Coil is 25% on specials, with a 30 second internal cooldown.
Stuff that I don't remember seeing detailed tests on, and/or forget what the answer was, that are of general interest to endgame melee DPS:
1) Mongoose
2) Executioner
3) Siphon
4) Blacksmithing Maces
5) Deathmantle 4/5 Set Bonus (was narrowed down but I don't remember seeing a conclusive proof)
There are probably others, but those are the ones that immediately spring to mind.
