Sodium metaborate ........ 2 g
Ascorbic acid .................. 4.5 g
Phenidone ...................... 0.05 g
Target pH = 8.05 to 8.10.
13:40 minutes for TMY2.

For a concentrate, mix everything except sulfite into 16 ml of propylene glycol.

A plastic Tablespoon was dipped into sodium sulfite,wiped off level with a card.Consecutive weights (grams) were:
25.3,23.5,23.5,23.7,23.3,24.5,24.3,24.3,23.6,24.0; Average=24.0g
I daresay 2 level plastic Tablespoons of sodium sulfite would be OK for this formula.
I am in favor of spoons because I remember Crawley's FX-55 developer, great developer, nobody AFAIK uses it because it calls for ingredients to be weighed out each time to make the working solution.
As there is no international spoon users would need to calibrate their spoon first.
And remember to use the multiplying factor if use 8-mol sodium metaborate,the formula above is for 4-mol.
