Although a smaller number of observations are included in these data, 

 the results show conclusively that there is no substantial difference 

 between the experimental peak-reading volume indicator and the 

 faster trigger tube arrangement, in their performance on actual 

 program waves.

The data from the tests have been presented above in the form which 

 most directly indicates the comparative performance of the two types 

 of volume indicators. However, a breakdown of the data with respect 

 to the types of program may be of interest and is shown in Tables 1
