Good luck with the grind — you're right there. An Ao5 of 15.29 with a 16.70 Ao12 means sub-15 is mostly about consistency now, not learning a whole new method.
What helped me most at that stage was splitting practice up instead of just doing timed Ao100s: a few slow, untimed solves a day focusing on tracking the next F2L pair while finishing the current one, then a block of timed solves where I only worried about not pausing between pairs. Cross + 1 is also worth drilling — if you can plan your first pair during inspection, even roughly, it smooths out the whole solve.
Your OH times are solid too for someone who doesn't do many events. Keep posting your Ao5/Ao12 updates here — seeing the Ao12 come down is usually the first sign the Ao5 is about to follow. Rooting for you!
