Sure, in this case:
My progression is:
When I get did RotK the second time with 2x32 i could not progress that rapidly. So when doing ladders to 4 and forth I had to repeat last weeks heavy before progressing.
Week 5 Grind 5x1,2,3
Week 6 Grind 3x1,2,3,4
Week 7 Ballistic 5x2,4,6
Week 8 Ballistic 3x2,4,6,8
Week 9 Grind 3x1,2,3,4 (that is repeat w6)
Week 10 gring 4x1,2,3,4
Week 11 Ballistic 3x2,4,6,8 (repeat w8)
Week 12 Ballistic 4x2,4,6,8
And above that, when starting @ 3x1,2,3,4,5 that is some serious density in the training. You might have to lower the later steps.
I.e. the first ladder 1,2,3,4,5
Second 1,2,3,4, 3 (fail rep 4)
Third 1,2,3,4
Next week try to repeat, OR increase the volume and do another 1,2,3 (or 4). Any progression is progression.
On the second part "I lack some fundamentals, flexibility, and stability. I believe I need to work on mobility routines as well as original strength resets type DNS work. But my issues is, if I do those exclusively I will not have strength gains, so"
THIS is the primary problem I see in this forum, to much nitpicking so people get lost on SS for 4 years having problem progressing from 16kg to 24kg.
I have done my part of getting lost in details and lost so much training time and progress.
I.e. "you need to have perfect press form before starting with a bell". No, you have to have good enough form. First reps might look ok, but rep 4 and 5 on the 4th ladder might look like crap. It is ok, strive to make it better next time.
"but i cant mlitary press it with perfect form" can you tempo-press it? if not can you pushpress it? If not can you jerk it?
Press what you can press, pushpress what you can't press, jerk what you can't pushpress.
Progress is progress.
For "mobility" warm up with a 5min flow (shoutout Max Shank) OR make a 5min flow earlier in the day. 5min a day is 35min each week... that's 1500 a year!
