Question: Divide-N-Hide Weight Limit i) on the lowest track and ii) Not using the Divide-N-Hide Adjustable Floors?

[Benjumin]

I found in my 2018 Nissan Rogue SL User Manual: "Do not put objects heavier than 165 lbs (75 kg) on the Divide-N-Hide® while in the mid position. In the upper position, objects should not weigh more than 30 lbs (14 kg)"

So, it sounds like
A) Highest Track < 30 lbs
B) Middle Track < 165 lbs
Then How about
C) Lowest Track < ?? lbs
D) Not using the Divide-N-Hide Adjustable Floors < ?? lbs (in Rogue with 8 Bose speakers, not using adjustable floors means you put the weight onto the subwoofer speaker)

Does anyone have any idea?
Thank you in advance!!
