Take this as an example
assuming 20% haste
Bad Juju – 0.50 RealPPM on landing harmful abilities and spells, and melee/ranged abilities and swings. No ICD.
rppm = 0.5*1.2 = 0.6
proc duration = 20s
uptime = ~20%
I'm fairly certain this is the correct way to calculate it as i've found several sources with similar uptime
Using the blue post formula,
ppm = 0.5
For example, if you have 22% Haste, it was 1.4sec since the last chance to proc, and you’ve got Windsong, then the chance to proc is 2(ppm) * 1.22(haste) * 1.4(time since last chance) / 60 (sec per min) = 5.693%.
haste = 20% (arbitrary value for calculation purpose)
time since last proc = 1
proc % = ppm * haste * (time since last proc) = 0.5 *1.2 * 1 /60 = 0.01 = 1%
At 2s after first proc, proc % would become 0.5 *1.2 * 2 /60 =2%
so at 10s proc % = 10%, EACH swing/spell theoretically has 10% chance to proc, which means, its highly likely to have a 100% uptime on this trinket, which of course is wrong, the trinket would be way too OP if so.
My question is, did i misinterpret the blue post formula? What does that resulted proc % really mean?
