Dyes
also need the correct laser power for the right amount of time in order
to produce a correctly sized hole in the dye. Too little power and the
hole will not form while too much power will cause the hole to expand
too much and possibly interfere with adjacent tracks. Dyes intended for
use at high speeds will be more sensitive than those used at low speeds

Ok that makes sense but one thing still remains a doubt. If Hi-speed discs
perform optimally close to their stated speed then burning a disc at very
low speed in respect to its max speed would suggest some form of data error
in some way or even coasters as many would say.

And perhaps vice versa at its max speed.
