One can project the likelihood of Rogue planets by the frequency of stars of various masses.
https://en.m.wikipedia.org/wiki/Stellar_classification
On the chart for every Gx V star mass 0.8 to 1.04 M⊙, there is twice as many Kx V stars 0.8 to 0.45 M⊙, and 10 times the number of Mx V stars 0.45 to 0.08 M⊙. Apparently if you go down to one third the mass of the Sun, you get 10 times as many stars, that is about 333 Jupiter masses, go down to 111 jupiters and its 100 times as many, and you can get 1000 times as many brown dwarfs of [33 jjupiter] masses, 10,000 as many 10 jupiter mass rogue planets, go to 3 jupiters and you can have 100,000 as many, and you haven 1,000,000 jupiters for every Sunlike star...
