It depends on your play style as well. I reach LITZ about 20% of the time I play that machine. I'm good, but I'm not THAT good. It just suits my style. I can gumball combo all day.
But this is on a machine without flaws. For example another TZ in town I play I have never gotten LITZ on, mostly because the ball comes off the wall half the time off the right ramp drop, making a piano shot impossible when it does.
But on both machines the scoop spit will not allow a safe deadpass, so I'm never getting that bonus. It's a 1-time or live catch every ball.
Also: No ball save, and harder settings, wide outlanes.
Ohh.... I've been known to bang-back, so I guess without that included my LITZ rate would drop to 10% maybe even 5%?
