Ok so some results here but I'm not sure if I did the test right, but at least I hope I did it wrong consistently 
Pool - Tested 10mL twice and both times got 24 drops to reach a pink/salmon mixture. 24*200=4800 which is 1000 higher than my SWG (did I do it wrong?)
Front spigot- 25mL (there is no 20mL so I did 25) 11 drops to pink/salmon
Back yard Spigot- 25mL - 13 drops to pink/salmon
Kitchen sink - 25mL - 15 drops to pink/salmon
