Linsear Write Formula #8

Closed yvlcmb closed 3 years ago

yvlcmb commented 3 years ago

It would be great to have the Linsear Write Formula added to the ReadabilityScores class. https://en.wikipedia.org/wiki/Linsear_Write

I appreciated the follow-up email, btw. 😄

The formula on Wikipedia is inconsistent with other implementations / sources:

Wikipedia says to subtract 1 if the raw score is over 20, these other references subtract 2. Unless you have other references that say subtracting 1 is correct, I'll subtract 2 to stay consistent.

Sounds good to me!
