Day 7: bits about diving

I've been trying to up my game prior to our team's big diving meet at the end of the month.

To remember the order of numbering, it's F-BRIT:
Front (100s)
Back (200s)
Reverse (300s)
Inward (400s)
Twist (500s)

The positions go
Straight (A)
Pike (B)
Tuck (C)
Free (D) but I haven't found a useful mnemonic for this yet.

(It's kind of like remembering the order in a medley relay: Back Breast Fly Free but at least that one's alphabetical)
