I've updated two files. gradesheet eg.xlsx now includes some extra formulaes, in particular ones that correctly fill in gradepoints and sums gradepoints while in progress, and I've added color coding to the final grades
IPA reference chart.pdf has added several corrections, including symbols which require leading zeros as opposed to those that don't, and I've added a column for Praat input codes. Almost added alternations to UCLABet that I use for Praat and in spreadsheets, but those are mostly just common English phonemes and major allophones. I need to do something like that for a course in the fall, so I'll still be working on it, but in the meantime it doesn't really belong in a reference chart for 'all available' IPA characters.
