You can still get 85-88 starts at 100%, up to 95 starts if you're willing to drop down to 90%... and up to 116 starts if you're cool with going down to 70%. It's a little frustrating that you can't get as many starts out of a player as you can relief appearances, as you can get 115 relief appearances out of an RP at 100%, but not out of an SP as they do fatigue faster in an RP role, and they are also limited to so many consecutive starts before a special appearance fatigue beyond the 70% of games fatigue kicks in... It's doable, but it takes some micromanaging early in the season to get your rotation all set up right for King to get both his 750+ IP and more than 81 starts.
My current project is to try to get 110 starts and 1,000 IP out of Clarkson... my first attempt got me 859 IP and 98 starts, my 2nd attempt is about 100 games in and I don't know yet how it's going to turn out.
