Yes I didn't notice rapture got nerfed further, so I was using 250% rapture as a factor. 150% rapture makes spirit a lot less powerful and stacking mastery or mastery/haste much less viable.

Disc already operates at a low HPM when you are spaming PoH with high overheal. Smite has pretty crappy HPM but you are still using it. Some of your spells will have low HPM, the question is how much can you afford to use them and does using them improve your HPS. If efficiency is all that mattered then we would only heal with rapture pws and penance and wait around for them to be available in between. What matters is how you can push out the maximum possible HPS in a real environment. Even with 150% rapture disc has stronger mana return than most other classes.
I dont think your calculation is relevant, because you are forgetting borrowed time. Chaining 1-2 spells on each borrowed time gives you a hefty haste buff. Also you are looking at something like 100k HPS. So PWS is 38% of your mana for 17.8k HPS which is about 18% of your HPS and an extra 5-10% haste on the rest of your HPS so an extra 4-8% extra HPS from borrowed time. so 22-26% of your HPS. Seems reasonable to me.
To put this discussion on a more solid basis lets actually sit down and figure out what is what in terms of our heals.
Using 24236k spellpower 60% mastery, 14% crit (+5 from inner focus on PoH), 10% haste.
PoH heals for 29073. PoM heals for 19809, penance hits for 26226*1.2 (since it will be buffed), binding heal heals for 39794, PWS absorbs 103895, holy fire hits for 33839, smite hits for 23184, cascade is up to 42391
Lets add the secondary stats:
PoH -- 29073*(1+0.15*2.6) = 40412
PoM -- 19809*(1+0.15*2.6) = 27535
Penance (atonement) -- 42927
BH -- 54279
Holy Fire -- 46156
Smite -- 31623
Cascade -- 57821
PoH HPS (5 targets) = 40412*2 = 80 824
BH HPS (3 targets) = 54279*2 = 108558
PoM HPCT (no 2set, no glyph) = 29595*5/1.5 = 90065
PoM HPCT (2set, no glyph) = 29595*6.1051/1.5 = 109971
Cascade max HPCT = 63332*10 = 63332 on 25 man and 63332*10/1.5 = 422213 on 10 man
Penance always applies 1 stack of evangelism with the 1st attack so the 2nd and 3rd never have less than 1 evangelism, so HPS coefficients for penance are 1.54, 1.6, 1.66, 1.72, 1.78, 1.8 for 0-5 stacks of evangelism respectively.
Penance (atonement) -- min: 42927*1.54 = 66107|| max: 42927*1.8 = 77269
With 5% more spell damage on boss -- min: 69412 || max: 81132
Thus at this point in time BH (when it is usable) has the highest HPS, followed by PoM (when it will jump 5 times), penance and finally PoH.
With the 2set bonus, its PoM, BH, penance, PoH
With the 4set bonus its penance, PoM, BH, PoH,
More importantly PoM is smart, BH has 2 clearly defined targets and a second target smart targeted and penance is a smart heal, which also stacks evangelism.
Thus PoH should only be used by disc when PoM, BH and penance are not usable/suitable. PoM should not be glyphed and binding heal should always be glyphed, because during heavy aoe damage, penance, pom and binding heal are your 1st port of call not PoH. PoH is now just a pretty crappy filler, while waiting for a CD or when BH can't be used. It is slow party limited and now it hits like a wet noodle. Even though I chose mastery here instead of crit, the values do not change if you change mastery into crit, because PoM, binding heal and penance scale in the same way as PoH with our secondary stats. PoM, penance and cascade can all be chained with borrowed time.
============================================================================
Now to put the secondary stat discussion to bed: Why is crit bad and why people just can't see to get it.
The return of crit is just impossible to calculate from the average values. Let me give you some examples.
Take a heal which hits for 40 and crits for 80
Now assume 50% crit rating. We predict that crit should contribute 33.33% to HPS if it has its full value
Here is a very skewed distribution:
heal crit OH h OH c crit cont
40 80 0 0 40
40 80 0 0 40
40 80 0 0 40
40 80 0 0 40
0 0 1 1 0
0 0 1 1 0
0 0 1 1 0
0 0 1 1 0
20 40 0.5 0.5 20
The bottom row is average values
Crit contribution: 0.3333333333, value 100%
Now take a different distribution:
heal crit OH h OH c crit contribution
40 80 0 0 40
38 72 0.05 0.1 32
36 72 0.1 0.1 32
32 56 0.2 0.3 16
28 48 0.3 0.4 8
24 48 0.4 0.4 8
24 40 0.4 0.5 0
20 40 0.5 0.5 0
30 57 0.24 0.29 17
Crit contribution 19.5%, value: 58%
Nice that the average crit is very nearly double the average heal, but the avearge crit is only higher than a non overhealing normal crit by 17.
So skewed distrubutions where OH is either very high or very low do not affect crit so much. In any uniform distribution affects crit dramatically. If the fight has a uniform damage distribution and you see crits being very close to a non-crit heal with zero overheal then you know crit has very little value.
Now lets take two 30s sequences, one with high PWS usage and stacking mastery (60%mast, 14% crit) and one with low PWS usage, but stacking crit (40% mast, 22% crit).

28.32039526 2.272727273 PoH
30.59312253 2.272727273 PoH
Modelling IF as 5% extra crit on PoH I get 120920.3038 for the high PWS sequence and 128235.2199 for the low pws sequence.
Theretically you would expect you expect crit to be 12% better throughput for all spells besides PWS and PWS is actually the lowest throughput spell in the sequence, so you would expect the mastery set to be below crit, way more than 12%, because you are replacing some PoH casts with PWS. However it turns out to be only 6% better, due to borrowed time. That is ofc with zero overheal and factoring inner focus in a way that devalues crit minimally. If I choose to replace one of the PoHs with inner focus PoH in each sequence I get 126233.9215 and 131808.3916. (4% difference). Crit gives you ~10% better spirit shell, so the question is whether you can offset that. I am not sure if haste works better with this sequence.
The only question is how much PWS usage we can support with our current mana regenation. One PWS synching with penance, solace and PoM may be sustainable.
