Sorry, I was referring more to FEF(/EFE) drills of longer durations, say 40-40-40 or 50-50-50, to work on specific race parts perhaps. I.e., not as a top speed drill. You opinion on this, please?

I would do 50F, 50E, 50F at times. these are often called “hollow 150s” and were often used by Alan Wells and later by Dan Pfaff.
