Hi Andy, The "value" of a problem is separate from the "fraction correct" that is kept for each student in the database. The "fraction correct" is a number bewtween 0 and 1 inclusive. Whenever WeBWorK is asked to compute scores, it multiplies the "fraction correct" by the "value" to obtain the score. So if a student did the problem correctly before the value was changed and then was scored after the value was changed, he or she should receive 4 points. The per cent correct reported to students is 100*"fraction correct" rounded to 0 decimal points and is independent of the "value". As Mike says, both the current and cumulative per cent correct are reported. I don't see how changing the value would have any effect on this (unless there is a really strange bug in WeBWorK associated with changing the value).
