Question about new ranked system (if someone from RITO can answer...)

Previous season i finished in plat 3 by playing mostly top and mid. Since im quite confident on my skills in all positions, this season i decided to climb on all 5 positions. As for that i found this statement from riot sapmagic: >When you queue as Fill, your LP splashing is stronger, which means you’ll be eligible for promotion series more quickly.

For starters, this has a very specific problem. Queuing fill will most likely get you into support, so you will still end up playing more games in the support role than the others.

And here's the question. What if i want to queue up at different role its time, say, i feel like queuing for top/mid, after two games i queue up as ADC/support, after 3 games as support/mid, etc. If i keep queuing by "cycling" through all positions, do i still get a stronger LP splash?
