Agree! If you are used to be slow, your body may not be able to feel comfortable when you move fast. Just try to throw 60 punches on your heavy bag non-stop as fast and as powerful as you can, you will soon find out that your "slow" body may not be ready for that. Try to spring as fast as you can for 100 yards will be another good test."slow is smooth". That mindset is flat wrong.
There are some extra requirement for speed such as
- a strong heart,
- fast muscle reaction,
- ...
that you just can't develop through your slow training.
