Thanks Matt, Andre
Was using my good ol' electric oven. Just one stone this time (Been using 3 recently to experiment with thermal mass).
I kept some notes on the dough which was an experiment in a 3 stage levain. Unfortunately it did not bring as much flavour benefit as I hoped.
Here it is for what its worth:
Stage 1: Refresh Starter1:1:1 ratio of starter:water:00 flour
Ferment @ 85F for 5 hours
Stage 2: Overnight Biga Naturale100% 00 flour
46% water
17% stage 1
Overall hydration ~50%
Ferment @ 60-65F for 15 hours
Autolyse/Soaker100% 00 flour
70% water
70% hydration
Rest @ 75F for 12 hours
Stage 3: Sponge (Final Levain)196% stage 2
100% 00 flour
96% water
2% salt
Overall hydration ~70%
Ferment @ 85F for 4.5 hours
Final Dough607% autolyse
366% final levain
100% 00 flour
11% salt (total salt ~2%)
7% water
Autolyse, levain and flour mixed until even (2 minutes)
Rest for 15 minutes
Salt and water sprinkled over the dough and mixed until fully incorporated (further 2 minutes)
Rest for a further 20 minutes
Dough kneaded to full gluten development (10 minutes)
Ferment @ 75F for 2.5 hours with 1 stretch and fold @ 1 hour
Dough divided and balled
Refrigerated at ~40F for 16 hours
Removed from refrigerator and allowed to warm up at room temperature for 3 hours
Baked (<2 minutes each pizza)
It's possible I should have left the dough in bulk for longer and not gone with retarding the dough balls but there were mitigating factors like...um sleep!

The final flavour was exceptionally mild.
Cheers,
