I definitely agree with you on feel,However, this is malmo's quote I was referencing

Being that your best mile is 4:42 I would suggest that you limit the repeats to 1200m max, and your tempo run to 3-4 miles. The point of the training is to get your body to runner faster, if you are mile and 2000m repeats and 5 or 6 mile tempo runs you are never going to run very fast.
So, while 5-6 mile tempos are great for longer distances,
if the original poster here is considering tempo runs with distances of 1, 2, or 3 miles it leads me to think that the athlete is focusing on shorter distances, and thus why I believe malmo's quote applies.
