To add on to what was said above, I find that it helps to do j.4D to make sure that after the RRC, the 83 doesn't pass over their head, causing you to whiff the j.S. Also, if you have trouble timing the j.S > 5H(2) and are capable of CH-confirming the j.D, on CH, you can just land from the 83 and do cl.S > 5H(2), skipping the j.S entirely.
