Drop your CI back to zero and modify descent speed to minimum. This will give you your latest RTA.
It is my understanding,(can't reference it ATM), that RTA speed is a percentage of ECON speed, which will vary with CI, (which will, of course, have some relationship to LRC, and will vary with weight).
The biggest factor though is to get on to it ASAP, as often your RTA will be generated close in, with little time to achieve what you want.
Speed intervene to minimum acceptable, while you play star wars in the box.
When you have a resolution , go back to VNAV.
It is also worth remembering while you are doing all this fiddling, that the top of the yellow gives you 1.3 margin and freedom from buffet up to 45 degrees AOB, unless you are in turbulence.
