No, 99th percentile for chase rate means only 1% chase less than the guy being discussed, so that would be excellent.
The in zone contact is always going to be an issue for Caissie, more than likely, because of the power, but because he doesn't chase, it's less of a problem. When you chase and miss in zone (Javy Baez comes to mind without any statistical back up here), that's what's really problematic.
