Measuring yeast in table spoons

[Pivzavod]

I have my washed yeast in pint mason jars and they are upto 75% yeast. I boil a table spoon to kill the bugs on it, take it out with boiled SS tongs and scoop a few spoons and drop it flask with some boiled & cooled water. Since I am using a really thick slurry I only need 48 ml of slurry as per Mr Malty's calculator. Each table spoon is ~15 ml so it takes ~3 spoons to get to what I need. Technically I am under pitching by ~3 ml but I use a stir plate and let the yeasties reproduce in the starter.

Is that an ok method to do?

As long as you're using good sanitation practices and making a starter, you're golden.
