How about we compress it further and assign

0 for unobserved fall
and
1 for observed fall?

We could then use a flag and define them with a single bit, a logic
state of false for unobserved and true for observed?

Or a null state for unobserved and true for observed?

Substantially more efficient than the system described -- You're
wasting almost half a dozen bytes!
