More CTL/TSS per week in general lends itself to more repeatability because you can handle more sets of the same workload. IMO. I base that opinion off of pros doing sooooo much volume and being able to do sooooo many repeats in races of stuff.
I thought that was a comment in the "Time Crunched Cyclist" book. The intervals done by a low volume cyclist mean you can do those, but not as many as a non-time crunched person can do. So the book claimed to "use your matches wisely".
