Exactly the same. I didn't do any A3, and I had too many A4 wipes that I only did 10-20 runs (can't remember which).
However, if you compare to hunts there are 17 ARR A ranks and 12 HW A ranks, and hunts spawn every 4 hours on average. An ARR A rank provides 40 allied seals, 15 centurio seals, 30 poetics, 10 law (IIRC) and a HW A rank provides 40 Centurio Seals, 30 Poetics, 10 Law. So, from A ranks if you are soley hunting, every 4 hours you get an average of
17*40=680 allied seals, 30*17+30*12 = 870 poetics, + 10*17+10*12 = 290 Law
Then there are 17 ARR S ranks and 6 HW S ranks. I found HW S ranks uncommon, but ARR S ranks spawned fairly predictably shortly after their 2-3 day cooldown. So we'll say 17 ARR on average 3 days, or 5.6 per day, so on average you will find 1 per 4 hour session above. So in that 4 hour session you will have 100 poetics, 100 allied seals, 30 law.
So per 4 hours at Hunts
780 Allied seals = 78% of an item
970 poetics = 143% of an item
310 law = 46% of an item
Total = 2.67 items
Optimally, with running Neverreap, let's say you do once per 15 minutes (unlikely to average 15 minutes unless you get a preset group, but for sake of argument) = 4x per hour = 16 runs in a 4 hour session. You'll receive 1600 law = 2.35 items - this assumes 0 wait time on queues, which is also unlikely.
That said, if you were able to make a preset group that wanted to farm Neverreap (doubtful lol), and you all put out your best with great DPS you could probably complete it in 10 minutes average, or 6 runs per hour = 24 runs per session = 2400 law = 3.52 items per hour.
However, more likely, you'll have 20 minute runs with a 5 minute queue (you'll be in a quickish queue with crappy DPS or queue as DPS and be in a longer queue) for = 960 law per 4 hour session = 1.4 items
Now with Alex, you need 10 runs per item (with some bonus law thrown in). You're probably looking at 7-10 mins average per run (including queue times etc), so I'll use 8 for this. That means in 2 hours you'll do 30 runs for a total of 3.44 items per session
