question about API KH test

Hadn't been testing for KH so I picked up an API kit yesterday. Instructions say add one drop at a time until the water turns bright yellow - mine started changing at 8, went yellow at 9 drops, got a little brighter at 10 drops (I think, kinda hard to tell) So do you read it at the first yellow change or a drop or two beyond that?

 

Parameters:

PH 8.0

S.G. 1.025

Amm 0

NO2 0

NO3 0

Calc 480

Temp 80

Read at the last drop that effects color. Ie if you have put 10 drops in and and its yellow...put one more drop and if the color doesn't change use the 10 drops as measurement not 11
