Theoreticaly, since like any dot, Ignite tick 1 tick more when refreshed (The current pending tick + Dot Duration) ... Which means 6 seconds of tick time, not 4.
So Theoreticaly at 1.3 second gcd you can fit 5 Hits in at max, in practice though its best to stick to 4.
Only way to increase the ignite yield from that is to
1) Have intellect/spellpower procs up (go go trinkets/Lightweave/Jade Spirit)
2) Potions
3) Have increase damage taken, debuff on the boss
4) Crits
1, 2,3 you can mostly kinda predict, 4 not really still assuming you have 33% crit rating on your gear you have 45% crit chance.
Which results in ~4% chance for 4 casts to crit in a row
20% to crit 3 times
36% to crit 2 times
22% to crit 1 time
Which means if you do crit your first Pyro (+Fireball), combust after the 4th
If you did not crit on the first pyro, you can fish for a fifth even sixth pyro as long as neither Pyro 1 or 2 didnt crit
Edit to add, you also get a minor advantage from Haste procs (Windsong) but that is completely negligable comparing to any of the above not to mention non-existing past patch 5.1
