yeap

lucy recorded 51.1  or 51.10
she's the closest to 51.12    just 0.02 away :)

anonymous · Answer

So is she both most precise and accurate, or just one?

jdoe0001 · Answer

hmmm both

the "most accurate" also means the "most precise"

it really means the same thing

anonymous · Answer

Alright, thank you. c:

jdoe0001 · Answer

hmmm actually

hold the mayo I think I see the nuance

jdoe0001 · Answer

Lucy is the most accurate time
she's the closest to 51.12

however, the most "precise" as in Precision, as in closest to a whole number
will be 51.769    since is closest to 52 by 0.769
