Well, when you only did those exercises three times a week, you seemed to add reps each day until you reached 5 reps/15 secs, then went down in assistance and started again with 3 reps.
If you're still following that ^, but the workouts are occurring a quarter of the time as before, then it will take you four times as long to reach your goals. So instead of December 2017, you'll reach those goals by December 2020? Is that the plan?
Or because they're occurring less frequently, are you going up by more weight/reps than you used to?
I think it's a generally good idea to train multiple movement patterns (just training Planches and OACUs has more holes in muscle training than I can count), but if you're now making progression steps 4 times as big as before to keep up with your Dec 2017 goal, then you might be more likely to get injured no?
Frankly I would fuse the lower body and upper body training days such that you only have an A and a B day, and I would rotate them three times a week. That's still less planching than you first started with, but it's more than you do right now. So you could make smaller progression steps and still meet your 2017 goal. It would also be just as rounded since you do all the same exercises, and it's not like OACUs and Planches are going to be detrimental to DLs and Squats anyways so.
