adding more citric acid

Is it ok to add more than 1 drop citric acid per drop of MMS?

For instance, while putting one drop of MMS in the glass to activate it maybe an extra half drop or whole drop got in, but I'm not sure. Can I use 2 drops of citric acid to make sure I have enough, even though this might result in 1/2 drop extra citric acid beyond the normal 1:1 MMS:acid ratio?

One drop off is not a big deal, but try to make them 1:1.

MMS1 is only 10% activated at 30 seconds, and stomach acid is relied on to activate residual MMS.
