RE: Warning: Some bots are not giving good vote even it says ROI: 10%, a method to learn if a bot is good or not

I use steemnow but multiply the SP by 100 to have accuracy as it avoid roundings:

For example here, with 15450 SP you get a $3 upvote. So for $0.03 you need 154.50 SP.

You can also simulate SP with this great tool:

That big circle on the top left with your vote power inside, you can click on the outter ring to show you the vote value at different vote powers.

There is a Simulate SP button on the right.

You currently have 226.43 SP which gives you $0.04 upvote at 100% weight.
