Re: Rule one of tea club
"You need jedi skills to do hot water with the tea bag first."
How so? You just need to be able to consistently pour the water onto the teabag up to the same depth each time. As long as you squeeze about the same amount of liquid out of the bag when you remove it, then you can reliably keep the same milk/tea ratio to within a couple of percent.
Variations in the type of milk used, or the contents of the tea bag will make more of a difference.
