For example: Play a game of Meerca Chase (Game ID 500) Time how long it takes you to get a certain score. Have that be your base time work with. Now with the time you recorded to get that score (say 30 seconds), Set the time range from 20-40. Then with the score you recorded (say 300), set the score range between 200-400.
Now don't use those exact scores/times since I just made them up. does that make sense so far?
Also, if you're using the SS to get an avatar/high score, make sure that the score you input makes sense with the time that you entered. The way I find out a good time to put in is to look up youtube videos of people playing the game for the avvie and find out how long it takes them. (For example, if you were going for Faerie Bubbles I would search up "neopets faerie bubbles high score (or avatar)" and see how long it takes the player to reach that amount of points. I hope this made sense >.<"
when you're playing games to figure out what kind of score and time to set (if you're not using a list which i dont suggest using lists) just play the game for a minute and see how high you can get your score in that minute then check the highscore board for any mods related to the game (some games can only have scores divisible by 10) and multiply the time by whatever score you wanted. make sure to double check your work by the way, being sloppy means getting abnormal scores and getting frozen.
