Speed of Sound

Laboratory nine, the speed of sound, went well with the usual drop in estimated sound speed from the 8:00 section to the 11:00 section. 8:00 had a 313 m/s estimate (332 m/s if y-intercept forced to zero). 11:00 had a low 218 m/s (299 m/s if y-intercept forced to zero). Not sure how to counter that speed drop, a drop that is consistently seen term after term.
