Yeah, sorry! I think with that scenario you would have to change their motivation for going. Like how we discussed in another thread maybe they could get the second half of the map instead, and either succeed, or even fail, like you suggested before.

The outer circle represents the shield, so Scenario B shows that he wasn’t trying to fly directly at the planet surface, but exit hyperspace in between the planet surface and the shield by approaching it at the planet’s edge/curve or whatever.

While still crazy lucky, you can see how that approach is a little less crazy than Scenario A. But, I guess that doesn’t fix your issue with the “fractional refresh rate” being a loophole that the story introduced when it was convenient. Your new idea alleviates that, but you’ll need a few new VFX, and it raises the question of why the X-Wings don’t pass through the shields the same way the Falcon does.
