Hi Scott,
More insights this morning, tracking any change and where the raise in RAM occurs:

Start: 136.8
One formula 141.2
Two 145.9
After 14.50 ram 148.7 no new formula
Modifying only text => 151.2MB
0:23.82  Then 151.3MB text only
0.28.45  Still 151.3MB and  Ctrl+S bring to 151.9MB
0.32.20  152.0MB and suddenly 157.0MB, a few characters changed
0.38.69  Some text, still 157.0MB, 2 times Ctrl+S
0.45.73  Some text, still 157.0MB+Formula Still 157.0MB then Ctrl+S after formula 161.7MB (second time such a change happen exactly at the same time) Opening a new document increase the RAM, but closing it after saving does not decrease it.
1.06.45 same effect Ctrl+S and change in RAM => 174.7 MB

Best regards,
Xavier

Thank you, Xavier. That's very helpful.

Do you use previews for the math?

We're trying to get an idea of what might be the cause of the memory use.

Thanks,
Scott
