These people may drop out over a very long time. Do you think they should be mentioned? If so, I don't know how to get the info. I think you will get to 80 sooner than a year.
Just thought - I could add a 'Weeks Without Charge' column and gradually build up the data.

I don't think rep changes if you are inactive. It takes me at least a year to go up by one and it just gets harder to increase. Inactive or unchanged time would be useful.

Thanks, I appreciate your experienced advice.
