This WHer has given me quite a bit of good advice compared to the rest of them. From what I've read here the figures seem about right but the CRUCIAL thing this person seems to have left out is that they seem to totally miss the fact that all these 'chores' are automated . So their argument of it 'not being worth the effort' seems to be left moot on that point. So see if you guys agree with the figures and amend them as required plus anything else pertinent to add to the discussion. Do those figures sound right or are they exaggerated from those experienced in BH?
