Just my opinion but I believe a great deal of the low 3.60's is in the clutch disc setup and having all that data log information after each run.
Once you learn to understand what it all means and how to apply that to the tune up and clutch setting interesting things start to happen.
I remember the days of painting the rear tires trying to determine the about of wheel spin and now its all in the data log system.
Having the data log really has made a big difference

I think another crucial piece to that puzzle is not only knowing what the data log says, but knowing the exact setup you had that produced that data. Don Higgins, who appears to no longer be a member of this forum, wrote a program geared for use by crew chiefs. I wonder if his program (and others like it) log that kind of information. If not, I can see there being some kind of spreadsheet, light weight database, or other homegrown electronic solution for this, in case the crew chief gets hit by a bus, or their notepad gets ruined.

It is NHRA mandated that they have crash recorders, too:

PRC Systems' website is unreachable, but I found this so you can see what it looks like:

Having either a 5 or 6 disk setup will work if you have each stage of the clutch setup to engage at the correct point on the track which changes run to run based on a number of variables.
It's my opinion that some teams have a much better understanding of the data and how to apply it in their setup.

It's whole package and being able to keep refining it.
NHRA has a pretty good handle on track prep and the teams have a good idea of what the track is or isn't.
It also it helps that they have had cool conditions for a test and two straight races. I'd imagine a few will have to do an about face if Gainesville is humid and warm.
I think most of the touring dragsters have made the switch to the 6 disc, we still run a 5 disc.

I believe there is a spacer being used between the can and motor plate !

As Alan and Mike said, same can with a spacer between the motorplate and can. They also cut out the back of the can so the throwout bearing can clear itself from all the lock up levers during the run.
