Welcome, Ainsley'sMom!
I've been reading posts and threads in the Maintenance Forum about how folks use the different calorie calculators, BMR, BMI, and all those things that are based on averages. It seems that many use the calorie charts and journal aspects of the sites but do not depend on those sites for accurate calculation of their own calorie needs.
I use a fountain pen and a pad of paper to keep track, making all sorts of notes about my research, on those pages.
I guess it depends on what kind of records you'd like to keep.
Sending you best wishes for success!
