I tend not to use the prefixes because then I could have 10 kids all with the same year of birth in the family navigator as it doesn’t have the >, < or ~ symbols.
I know not all the dates are accurate but a starting point is better than nothing to me. When entering new entries in Reunion, there is a warning popup to say birth is before/after a range of the parent (too young, too old) or after their death. But confess sometimes I enter in hopes I find something to substantiate the date.
