Code:

 - 1:50:00   TI-66         

 -   58:20   TI-58C      

 -   56:15   SR-52          

 -   43:40   TI-59          

 -   18:25   TI-88     

 -    3:53   TI-95

I decided to do a side-by-side comparison of my own. I used the program for determining the factorial of a number (i.e. x!) as listed on page IV-74 of the Personal Programming book. I typed the program into each of my two calculators (TI-58C and TI-59), verified they were identical and set them both up to compute 69!

The times were 30.88 seconds for the TI-59 and 38.88 seconds for the TI-58C. This gives a factor of about 1.27 to 1. The stats posted in the quote were around the same ratio (about 1.33 to 1) between the two calculators.
