Shield regen is not divided per face. Each face on the FR86 recharges at 4k. I just did a start up test it takes 18 seconds for all 4 face to go from zero to 100. This would actually explain why my front shield goes back to 100% so fast.
Edit:
My bad, that test isn't useful. But I do believe that the 4k regen applies to any face. So if all 4 sides are damage than the 4k would be divided, but if only 1 side is damaged the full 4k will be applied to that one side. It would explain why my front shield charges so fast.
Hmm, well, I looked at few Camurals videos

shame he didn't damage the shields more, but at 6:00 the banu defender took 96*2*3 = 576 damage.
The shield in question has 419 shield regen. If it was divided by 4, it'd take 5 seconds to heal the damage. If the whole regen applies, it'd take a bit over a second.
No matter how I look at it, seems like it only took a second to heal back to full, meaning you appear to be correct about the full shield regen applying.
As a proud owner of a starfarer Gemini, I wholeheartedly welcome this news. Overclocked FR-86 has 6772 continuous shield regen.
So, let's revise.
Sabre with 4 gimballed overclocked CF-227 Badgers can't even dent the 600i with FR-86, The shield regen completely overwhelms any damage.
Sabre with 4 fixed overclocked CF-337 Panthers can not even dent the 600i with FR-86.
Sabre with 4 fixed overclocked Attrition-3 (3698 dps at 299m) at optimal distance can't even dent FR-86.
Sabre with 4 gimballed Dominance-2 scatterguns (4675 dps) will barely dent the FR-86 (4369 regen) with 306 dps.
Sabre with 4 gimballed overclocked Dominance-2 scatterguns (7013 dps) will barely dent overclocked FR-86 (6772 regen) with 241 dps.
Sabre with 4 fixed overclocked Dominance-3 scatterguns (8568 dps) will destroy one shield face of overclocked FR-86 (6772 regen) in 10 seconds with 1769 dps.
I mean, the scatterguns are still pretty much OP, and for Sabre it seems like they're more or less the only choice against a 600i with FR-86. I mean, sure, there are ballistic weapons, but FR-86 at full health reduces even that damage by 95%.
Meanwhile my reliant setup would be 2 gimbaled Dominance-1 overclocked (2310 dps) and 4 Dominance-2 overclocked (7012 dps) for a total of 9323 dps. While I could get 1195 dps more by swapping those two gimbaled dominance-1s for fixed dominance-2s, the Reliant 2x2 wing mounts are gimbaled and I don't want mix of gimbal + fixed. Besides, Mixing dominance-1s gives a better stagger effect.
Anyhow,
My reliant (9323 dps) vs 600i with FR-86 (4369 regen) would take one shield face down in 4 or 5 seconds
My reliant (9323 dps) vs 600i with FR-86 overclocked (6772 regen) would take one shield face down in 8 or 9 seconds.
Lessons:
1. Scatterguns are OP
2. Always overclock the shield
3. You are either entirely invulnerable or die in a few seconds.
