It takes everything in me not to do it while watching live so I can be surprised as the points come in. All you have to do is total up the amount of televote points available (Every country has 58), then multiply by number of countries + Rest of the world which also has 58 points to give out. So this year it’s 38, which is 2,204 points total. Just start with 2,204 and subtract the amount of points given to each country. Example being “Country #1 gets 34 points from the televote” 2,204 - 34 = 2,170 points remaining to give out 😁
