GC ~ every 20 s = 0.05 hopo/s
=> approximately 0.53 holy power per second at 11000 haste rating (25.9% haste). So you would expect to be able to cast a finisher about every 5.66 seconds.
J is not a 6-second cooldown. It's a 6.75-second effective cooldown because of CS clashes, and thus turns into a 6.75/1.2588=5.36 second cooldown with 11k haste.
Alternatively, it's just easier to think in terms of unhasted values.
CS HoPo = 1.12/4.5 = 0.2489 HP/sec (including GC procs from CS/HotR, hence 1.12 instead of 1)
J HoPo = 1/6.75 = 0.1481 HP/sec
GC: assuming 30% avoidance, it's a 12% chance per avoid, or 0.12*0.3=0.036=3.6% chance per boss swing. For a 1.5-second swing timer, that's 0.036/1.5=0.024 HP/sec (nearly negligible, and worse for longer swing timers, time off-target, or bosses that pause to cast).
Net HP gen at 0 haste: 0.2489+0.1481+0.024=0.4210 HP/sec, which is also your SotR uptime (42.10%).
Net HP gen at 11k haste (25.88% haste): (0.2489+0.1481)*1.2588+0.024=0.5237, or 52.37% SotR uptime. (note that the avoidance contribution to GC does not scale with haste).
