Sometimes it's chart #1... dr1f or dr3f
Sometimes chart #2...el6f, fl6f,fl5f,gl6f,gl5f,hl6f and hl5f.
The two places on chart #1 , can happen independently of one another but all the places in chart #2 happen at the same time, immediately after taking downward pressure off that side such as standing on one leg or standing up straight after bending forward to brush my teeth, etc... the instances chart #1 are more from flexing as in exercising, walking doesn't bother me but getting up off the floor or out of a chair does, even if i use something to aide in the process, ie chair arms etc, i have been sitting in an old time rocking chair with a lawn chair cushion on it for the last month but didn't have the pain in chart #2 until before i got the rocker, and just before i started physical therapy.
I went to my employer last Saturday to experiment with climbing into the truck and trailer, it was painful but doable if i used my good leg to push myself up but impossible with my bad leg. I need to perform that task at least 25-30 times a day, and that's just getting in the truck, double that for getting out.
