Writing a bunch of if statements is a worthless kata idea. Moreover, at least a dozen of these can be found if you search with these filters.

issue:

• edge case missing: 0. And some negative values too (to check correctness of implementations using arrays)

suggestions:

• you don't need to separate the 2 batches of tests, since they are all fixed
• you could add a small batch of random tests with random invalid inputs ("well..." again, considering the range of valid inputs...)
• look at one of the katas (recent) you already solved to see how random tests are implemented

hi,

• sample tests missing
• 5 "Lumbar" -> "5 Lumbar" (description)
• (I was about to ask for random tests but... maybe randomized ones, on a random incomplete set of inputs...? :/ well...)
