9 minutes is good - your temperature is right about where you want it.
Humour me and follow the ratios I use - I long since stopped using sugar and olive oil - sugar makes the bases heavy (the yeast uses it all up quickly, in preference to the gluten - rises quickly on knockdown and proof but does not rise well in the oven - sugar seems to caramalise) and olive oil stops the base from being too crispy - ends up being chewey though...
Cake flour is a low gluten flour, reduces the elasticity of the dough as well btw.
Try 3g dry yeast
325g water (warm, about what you would bath a baby in - too hot you kill the yeast)
500g flour - If you can lay your hands on a Tipo flour and a plain flour (cake) 50/50 mix is good, otherwise stick with the flour mix you are using - our local supermarket has Tipo 00 here in Aus, its pretty common.
Knead, allow to rise (twice the size), split into 3 175g (ish) boules, proof to 1.5X size, stretch boules by hand - 175g boule makes a 10" (roughly) 2.5-3mm thick.
This is a foolproof version that always works well for me - measure by weight not volume for consistency as well...
Bet your family is sick of pizza now

I'll have to break out my oven again, I'm building a deck and its in the shed at the moment ~ hanging out for a good home-made pizza again, my daughter is pestering me to make some!
