Bookmarked your site, very informative.
But there are profit differences with other asic profit sites

I just checked the website out right now and it looks accurate, assuming a miner is more profitable than the other tomorrow is the website going to automatically update itself? I've only seen this with Nicehash before, thanks for sharing I will bookmark right away.

Does your website not support showing a hash rate below 1 H/s? I checked GRIN profitability on other websites and it seems like there is quite a huge difference between your data and theirs. I assume your code round the hash rate up, or it can't show any lower than 1 H/s, but then your 2080 TI is ok, while the rest is not. Maybe you should double-check it since most GPUs don't reach 1 H/s even at max TBP according to other sources.
