Isn't it s/(s+g), where as you correctly say, g is legit account who want to buy? 1000 people want to buy a machine, 10 of them are scalpers, that's one percent on average? s = 10 and g = 990.

I feel like I'm having a slow day XD



Yes, you are technically correct (the best kind), but when s is much smaller than g, then s/(s + g) and s/g are approximately equal.
