Amount of mother starter culture?

[qdog1955]

After making some mother starter cultures using Sailors wonderful tutorial. ( LH100 and T62 ) Frozen into 1oz. cubes.  I Need some clarification on the amount of cubes used in a recipe. Is the inoculation percentage---the 1%-1.5% and 2%---the amount you are adding to your milk? If so, how do you determine what percentage to use on any particular recipe? Will the higher percentage work faster? I have tried this only once, at 1% and the acidification seemed really slow. Any help would be appreciated.

I also use ice cubes but to be sure that the culture is active I place a cube in half a cup (for a small cheese) of milk at room temperature a few hours before I want to use it. (Work clean and cover the cup)
After a few hours all the milk can be used as mother culture. You can smell that it is sour.
