I mean... Fire 1 extends the timer long enough to cast 3 more Fire IVs and an AF3-enhanced Blizzard III, does it not? In itself that's 10.75 seconds of casts, assuming no extra GCDs and a base spell speed.
8.4 + 1.75. B3 is cast 50% faster (3.5 base)

In a 3 1 3 set up, you're at

13s AF - 8.4 (F3 x 4) -2.5 (F1) + 10.9 (2.5 doesn't really count as it was for the F1 GCD) - 8.4 (F4 x 3) - 1.75 (B3).

Net amount: 23.9 - 20.55.

If we only use 8 gcds for comparison (F3, Thunder, F3, B3)

13s - 8.4 (F4 x 3) + 6 (Burst Clipping) -2.5 (Thunder 3) -8.4 (F4 x3) +6 (Burst Clipping) -1.75 (B3)

Net amount: 25s - 21.5
