dilluting problem?

[wolfpac]

i dilluted a batch of 93% bw in a gallon glass jar down to 40%.both the neutral and the alcohol was room temp.i funnel off into a half gallon and the last was split into 2 smaller fifths.we took the last fifth and put in in the freezer for later.i went to the freezer for one more with the mrs and it was like a frozen slushie so i let it warm up and checked the abv and it was 28.5 so i checked the first bottle and it was 45%.my question is does water settle down,should i slowly keep it stirred with say a wooden spoon while i funnel? i have surched and advanced surch but most problems are with cloudy results.this was nice and clear,sorry for too long of a ?
