Now that I've sorted out the temperture of water when mixing stock A I've noticed that Sandy King states that HP5+ should be developed in a dilution of 2:2:100 instead of 1:1:100. If for 1:1:100 I use 5ml + 5ml + 500ml water, then the 2:2:100 would be 10ml + 10ml + 1000ml water. Aren't these the same with more solution being the only difference with 2:2:100? Am I missing something here?
