There is no difference in stick forces or "break out" as you're calling it
between CAS, DEL, or MECH modes. Perhaps you're talking about the feedback
force that is added when the stick is displaced from its neutral position?
That is certainly not a "break out."

That is, too. That's the definition of break out force, the force you
have to overcome to leave the deadband.

What do you think break out force is?

Don't get me started on stick force shaping, as I spent some serious
flight time and money looking at a variety of schedules for pilot
cueing. I can probably tell you more than you want to know about how
pilots perceive the cues, although the most interesting part is how
they can fail to consciously notice a major cue, even when it affects
their technique.

How many F-18 hours a year in the air are you and monkey getting Woody? 50?
20?

Per year? Absolutely ZERO in MECH, more than 150 or so in CAS, less than 1
in DEL (spin recovery mode).

Keep it that way. The Plastic Bug flies miserably in MECH. It was a
big deal when they finally trapped in MECH, in fact. Before that, it
had meant diverting to land. When Tom McMurtry had to land one of
ours in MECH he cheerfully declared it to be one of the worse control
modes he'd ever flown, not counting those he'd flown for me when we
were doing the PIO work.

I thought DEL was a reversionary mode for more than spin recovery,
though. Doesn't the Bug drop into DEL when the MC faults? It's the
spin recovery mode that overrides the surface limits for spin recovery
when the yaw rate goes over some limit (40 deg/sec, maybe?), isn't it?
