So I to use it in starters. At what point do you add it if using it to help blowoff?

After I oxygenate I add 10 drops. I want the foam when oxygenating since it helps dissolve more oxygen.

When I say conversion efficiency I base that on the estimated max that the maltser lists (which is in itself usually 80% - 85%), preboil volume and gravity. So after doing the math, lets say my theoretical max gravity was 1.050 preboil, and I measured 1.046 I would be at 92% conversion/lautering efficiency (I add in lautering because it matters how well you do the sparge in how much converted sugar you collect, also 92% is the highest I have ever achieved on a brew day so far). I don't think you can actually hit 100% IIRC.

That's not Conversion Efficiency, that is Mash Efficiency, which is Conversion Efficiency x Lauter Efficiency.Kai's chart or the equation I explained here are two ways to determine the expected mash gravity (what will become the first runnings), which can be used to calculate Conversion Efficiency. Here's that equation simplified:100% x (gravity of mash) x (mash thickness in pounds per gallon + 0.075 gallon) ÷ (potential yield of grain)
