Ken,
If I look at the 0.250" lifter raise duration for what you sent to me which is labeled the Elgin 909 / 744 I get 76.3 degrees

If I look at the 0.250" lifter raise duration for what I have for what is called the SP3 OLD version I get 72.5 degrees

If I look at the 0.250" lifter raise duration for what I have for what is called the SP3 NEW version I get 62.5 degrees
