Thunder II - Fire III - Fire I until 300 MP - Swiftcast Flare - Convert - Fire I - Fire III (proc)

The last Fire III is what I am talking about. A lot of people go like Thunder II - Fire III - Fire I until 300 MP - Swiftcast Flare - Convert - Fire I - Blizzard III - Thunder II ...
What I mean in my rotation with the proc is that during my last Fire III before using Blizzard III, I press Fire III button in case a Fire III proc appears. I do this very swiftly. If there is no proc, I use Blizzard III immediately since there is almost no loss in time.
What I have seen people do to counter a proc going to waste (before MP runs out) is the following:

Thunder II - Fire III - Fire I until 300 MP - Swiftcast Flare - Convert - Fire I - (Proc here but it's not used) - Blizzard III - Thunder II - Transpose (to get 1 stack of Fire - Fire III PROC.
As I have explained, my method is better (I think) because the fire III procs hits harder and there is a GCD in both rotations.
