I ran about four hours of Dragonspine testing on the 2.4 PTR, and saw several procs occuring about 20 seconds apart (from start to start, not from fade to start). I don't have any screenshots, but here's an excerpt from the combat log file for the shortest start-to-start time:

The buff comes up at 14:44:35.406, fades at 14:44:45.484, and comes back up again at 14:44:55.421, for a start-to-start time of 20.015 seconds.

If I counted all the eligible swings (ie, all white strikes greater than 20 seconds since the last proc) and all the procs that occured, I can calculate the proc chance for an individual eligible attack, and convert that to a PPM for the trinket. This gives something pretty close to 1 PPM. So, if you were autoattacking with a single weapon and never missed, you'd get on average 10 seconds of uptime for every 20 + 60 seconds.

Here's how I model uptime for a real life scenario:
The chance per second that the MH will proc is
MH_PPS = 1 PPM / 60 seconds * (1 - %miss - %dodge).
since the proc chance adjusts for hastes to maintain a constant PPM. Same thing for OH:
OH_PPS = 1 PPM / 60 seconds * (1 - %miss - %dodge).

Specials (Bloodthirst, WW, etc... maybe Windfury too, I haven't tested) use the MH base weapon speed to calculate proc chance (I'm ignoring offhand hits from whirlwind - I haven't done any testing on that either).
Special_Proc_Chance = 1 PPM * MH_Base_Weapon_Speed / 60 seconds
Special_PPS = Special_Proc_Chance * Specials_Per_Second * (1 - %miss - %dodge)

Then all three PPS values add to give the total chance that the trinket will proc in any given second:
PPS = MH_PPS + OH_PPS + Special_PPS

The average time to proc after the internal cooldown comes up is then 1 / PPS. So, our uptime can be calculated as
Uptime = 10 / (20 + 1 / PPS)
using 10 seconds up with a 20 second internal cooldown.

I guess there's a few points in there where I made some approximations -- using a proc per second instead of by swing, and just adding the three PPS values -- but the individual proc chances are small so I think that's a valid simplification.

again at 14:44:55.421, for a start-to-start time of 20.015 seconds. If I counted all the eligible swings (ie, all white strikes greater than 20 seconds since the last proc) and all the procs that occured, I can calculate the proc chance for an individual eligible attack, and convert that to a PPM for the trinket. This gives something pretty close to 1 PPM. So, if you were autoattacking with a single weapon and never missed, you'd get on average 10 seconds of uptime for every 20 + 60 seconds. Here's how I model uptime for a real life scenario: The chance per second that the MH will proc is MH_PPS = 1 PPM / 60 seconds * (1 - %miss - %dodge). since the proc chance adjusts for hastes to maintain a constant PPM. Same thing for OH: OH_PPS = 1 PPM / 60 seconds * (1 - %miss - %dodge). Specials (Bloodthirst, WW, etc... maybe Windfury too, I haven't tested) use the MH base weapon speed to calculate proc chance (I'm ignoring offhand hits from whirlwind - I haven't done any testing on that either). Special_Proc_Chance = 1 PPM * MH_Base_Weapon_Speed / 60 seconds Special_PPS = Special_Proc_Chance * Specials_Per_Second * (1 - %miss - %dodge) Then all three PPS values add to give the total chance that the trinket will proc in any given second: PPS = MH_PPS + OH_PPS + Special_PPS The average time to proc after the internal cooldown comes up is then 1 / PPS. So, our uptime can be calculated as Uptime = 10 / (20 + 1 / PPS) using 10 seconds up with a 20 second internal cooldown. I guess there's a few points in there where I made some approximations -- using a proc per second instead of by swing, and just adding the three PPS values -- but the individual proc chances are small so I think that's a valid simplification.
