Reaching a blocking point - Failure PE 11 Week 10

I reached a blocking point.

 

I'm in week 10 on Wrist Wall Handstand - PE 11 4X60.  I was able to complete 48 sec holds, but cannot complete 60 sec holds in a timely fashion.

 

Should I continue the week 10 requirement for the remaining 2 weeks of the cycle and start back at week 9 again??

 

What do you do when meeting a road block?

Hey, not a lot of time right now but check this post I made in another topic. Lots of links for plateau breaking.
