We are thinking about setting up a 'red thumbs/green thumbs' ratio of 20% (meaning that if the ratio of the number of red thumbs you have given over the number of green thumbs you have given is 20% or more, you need to give some green before giving any more red).
For example, if you have given 10 green thumbs and 2 red, your ratio is 20% so you cannot give a 3rd red until you have given (at least) 1 more green.
After that you'll have given 11 green and 3 red: your ratio will be 27% so you won't be able to give a 4th red until you have given (at least) 5 more green.
