Without memory safeguard you are left with nothing after the 991EX times-out after a few minutes of non-use, or if you must change calculator Modes, —and then return to your original Mode.

It's why I never bought one.

Yup, the 36X Pro will happily save all of your stat data until you deliberately clear it. Casios and Sharps, as nice as some of them are, will rarely do that if they aren't graphers.
