Help! Need some guidance when it comes to buzz testing injectors.

I have a 2002 psd 4x4 w/ 7.3l that has around 240k miles. I literally just bought the truck. Well as per my preventative maintenance strategy I changed all fluids and check everything using the forscan software on windows. The truck doesn't have any codes or anything wrong with it. I was just curious about the state of the injectors. When I do the test the 1st buzz sounds normal but the other ones are barely buzzing. Like extremely faint buzz but they do all buzz and the software completes the test and says there ain't a problem yet they barely buzz. Is that normal or what is going on here? I'm going to do the 50c mod now so ima have covers off to inspect the harness connection underneath. Any ideas would be appreciated thanks

I believe there should be 9 buzzes. All 8 the first time, then each one should be an individual injector buzz. So yes the first buzz should be louder.
