make 2 cols, 1 for score, and 2 for # of scores. then select the avg using mysql's avg function. take that number, and add the current score, then just get the new avg by taking the old one and / it by score# + 1
something like that, im not thinking clear or logic.. but use some of that math stuff you learned in school 😃 ( i forget how to modify an avg )
OOOOR, save all the scores separated by a ',' , then when u get the result - explode it and add all the array values together? could work
