Variability in lac fusions assays

I am seeing great variability in parallel identical E.coli cultures
which have full length lacZ fusions to a strong promoter (ParaBAD).
Anyone who has struggled with this please send me a note.

(eg. how many Miller units is "too many", preferred media, induction time, ect.)
