Speed Endurance "Stacking"

today i had a speed endurance for the first time at my indoor track and have found that the turns are WAY to sharp to go full speed and when going around them i am slowing down noticably even for the firsy, most fresh run.

so i am asking this…i Have read this in Brent Mcfarlene’s “The science of speed and hurdling”(fourth edition) that when he has limited space, he used “speed endurance stacking” which is for example, 2x5x60m with 30 seconds rest each rep and 4 minutes rest each set at 95-100%. Would this kind of endurance training have the same effect as say, 6x150 at 95-100%?
