Please explain the improvement in non-SG arena income. When I go at non-SG's at PFUDOR I don't recall seeing my credit drops increasing. I also still only largely get superior or exquisite trash, and while PFUDOR generally raises your odds of a leg or mag drop (and thus a jackpot), my only time ever getting an actual jackpot-level item was a staff that dropped in Normal mode (I think on a SG arena, but it could happen in any arena).
I don't experience the profit levels in PFUDOR non-SG arenas that I get from selling SG trophies.
Drops improve from:
- Scavenger
- LOTD (barely)
- Quartermaster
- Archaeologist
- Crystarium
SG trophies are the main profit of SG arenas, but as you can see, they aren't affected by any of these. After training/perks, there are some drop benefits from the ordinary monsters in SG arenas, but there are generally few standard monsters per round in SG arenas, and the rounds take longer than usual, so the overall improvement in SG arenas from training/perks is minimal.
On the other hand, in ordinary arenas and GF, all 4 of those drop improvements moderately help; there are generally more standard monsters per round, and none are particularly tanky, so it doesn't take long to finish the round. But - in arenas, a substantial fraction of income comes from credit drops, which isn't affected in any significant way by training/perks. So by training, income per round increases more in standard arenas than it does in SG arenas, but not by a whole lot.
GF is where those training/perks really shine, because (static) credit drops are minimal, and [crystals, equip drops, artifact drops] together make up the vast majority of income - all of which are substantially improved by those drop improvements mentioned before. So getting training/perks
most increases GF income.
Note that this is
rate of change in income, not
absolute income; even with training, GF might still not be as profitable as certain other battle series'. Check Income Summary to get absolute numbers.

I have not ever completed all 1000 rounds of a Grindfest. Considering that (thanks to my ping) it takes 15+ minutes to do DWD on normal while just plowing right through and ignoring all gems, I absolutely shudder at the time it might take to do a PF Fest. Then I'd have to recover my stamina with stupidly expensive energy drinks. I haven't done the math on what 1000 rounds do to your stamina but I know 24 hours isn't enough to recover from that; so one whole GF per day has me at 10 stamina within what, a week or so?
GF is 1000 rounds, which requires 20 stamina if you're below 80 (30 stamina max). So you'll recover enough stamina to play a bit more than one GF per day, without using any energy drinks.
