When I set the price to 0.5 I expected my money to increase by 0.5 whenever I sell one nail. So: Nails -1, $ +0.5, Nails -1, $ +0.5.
But it was more like this: $ +0.1, $ +0.2, $ +0.1, Nails -1, $ +0.2, $ +0.2, ....
price is per nail. if you sell like 5 nails a second at a 0.10 price, you get 0.5 a second.
That was the strange thing. I set 0.5 as price. But funds raise in smaller steps. For example from 27.04 to 27.32.
Only thing I could explain this with is if there is one sale every 5 seconds and the 0.5 are split in 5 updates, one each second.
