In light of my readings, I don't plan to increase dosing but I am curious about how much vinegar to dose. I gather it's not even close to the 'recommended' vodka dosing in light of how high your doses are.
2ml/ccs of vodka is a very low dose in any case. but if NO3 and PO4 are low I wouldn't increase it . Typically foks settle in around .4 to .7 ml of vinegar pr gallon which is equal to .05 to .09 ml per gallon of vodka.

To figure vinegar and vodka just multiply vokda by 8 to get an approximately equal vinegar dose and divide vinegar by 8 to get an approximately equivalent vodka dose. This accounts for the dilution. Vodka is 40% ethanol,the carbon source, and 60% water. Standard white vinegar is 5% acetic acid, the carbon source, and 95% water.
