I have the following sentences and not sure if one of them is better than the others. So, there is a threshold for user participation. If user participation is less than the threshold then I call it they under-participate
. I believe this is fine.
However, users can also just do the threshold or more. This is the part with which I have problems phrasing. Any of the followings is acceptable and conveys the meaning that I meant to:
... users who are likely to under-participate and users who are likely to participate as required or more
... users who are likely to under-participate and users who are likely to participate as required or go beyond/exceed the expectations
... users who are likely to under-participate and users who are likely to participate sufficiently as required for the worst case.
UPDATE: FURTHER DETAILS
Let's say users are supposed to post 3 replies in a discussion forum. However, some of them had less than 3 replies whereas others have posted at least 3 replies. Here is a more generic template:
... aims to identify users-with-less-than-3-replies versus users-with-3-or-more-replies.
So, the users belong to either group. First group under-participates
. But, I am having trouble finding a phrase to concisely indicate the second group. For example, over-participate
would not work since participation at threshold level is also fine actually. Also, it has negative connotations.
