Starting rapid recall – should we break from RS in the meantime?

I searched for an answer in previous posts but couldn’t find one. 11 yr old needs mult facts and 9 & 7 need addition. They get the concept just don’t have them cemented. Should we break from Rightstart while we do RR or continue with both? This week I have been doing both while substituting RR for some of the RS warm ups. What do you think? What was your experience? Thanks!
