Russian Strength Skill Continuation Questions

Hi coach, once again thank you for your amazing articles and support.

I have completed 4 cycles of your Russian strength skill programme and was going awesome then I went on a 10 day vacation. Now I am back into it and am struggling with weights I was comfortable with before.
What are your suggestions, I was just going to retest and start again, and was this programme written to be used for a long period?

Thank you in advance CT
