OK so your final answer is?

If R just muffs the kick into the endzone it is a touchback. The kick hasn't ended and any scrimmage kick into R endzone is a touchback.

(It is late now but I'll take a shot at the bat)

If R illegally batts the kick into the endzone, it is a post scrimmage kick foul. R's foul meets all the qualifications of PSK. The kick isn't ended so the ball into R's endzone. Therefore, still a touchback. The basic spot is the R20, so first and 10 for R on R10. If I blew this, BE KIND!

Your inclusion of "Ball being nearly at rest" suggests to me that you are considering a new force. Force is not a factor in scrimmage kicks into R's endzone. Regardless of force TOUCHBACK
