My thoughts on making stannous chloride, would be to saturate the HCl.
Whatever proportions of acid and water you use, the most reliable use of it comes by always making it the same. That way, the extent of darkness will give you an idea of how the Au solution you're testing, compared to others you have done, rather than representing the strength of your stannous testing solution.
