Now you have to build a bike in MotoGP to reach the potential of the tyre and if you lower the tyre performance by 30% every manufacturer would be able to reach its potential. To cheapen things up, make things easier and make the racing closer they just need to make a tyre that will go the race distance which has less grip.
If you want closer racing, then that's probably the easiest way. Also the manufacturers wouldn't need to spend so much money on development and that would mean that we see more bikes on the grid rather than the CRT ones.
I'm not for or against CRT, they make up the grid but it is basically another class and by changing a couple of things around it would cost the factories less money to race and they would be able to afford to put more bikes on the grid.
Thanks Ben, and good luck tomorrow...
