Optimal Speed

Hi everyone!!!
I'm the kind of guitarist who's been playing for a long time and who has just started practising seriously only recently...
Now I'm working hard on correcting the mistakes i've been making for such a long time

I'd like to know if, in exercise lessons, there is an ideal speed you're supposed to reach.
For instance, I'm now practising Danilo's lessons series ( HAND SYNCRONIZATION, RIGHT HAND BASICS, FINGERS INDEPENDANCE):

IS THE SPEED SHOWN IN THE VIDEO THE SPEED I SHOULD AIM FOR, OR SHOULD I PLAY IT FASTER?

Thanks in advance for your suggestions

Ps. Grazie degli ottimi esercizi Danilo / Thanks for the excellent exercises you shared with us Danilo
