What are most peoples needs for the Y3 to pull a certain quantity of rolling stock? I would say that most people would be pushed to put 20 freight cars behind one of these except for those that are lucky to have the space for a large layout.

What would be interesting now is for someone with a Y3 to remove the boiler shell and then slowly load it up with traditional AF freight cars and see where the break point would be for a maximum consist. If it was able to pull around 30 then I think it would meet a high 90’s % for most people. Traction tyres would enhance its pulling capacity to assist a plastic shell.

Articulateds like the Y3 are somewhat of an exception having two sets of drivers and motors.  If they don't pull heroically, there's something definitely wrong.

All I can report is when I run my Flyer Alton Limited (4-6-2 and the 6 heavyweight set passenger cars,) the locomotive slips on level SHS R24 curves, (no slipping on the straightaways) even with it's almighty metal boiler and traction tires.   It doesn't slip excessively, but it does slip and slow down.  I imagine slipping would be worse on R20.  If I were to set up grades, I'd probably have to cut out one or two of the passenger cars.

Now personally, I have set a 13 car maximum (including caboose) on my freight trains, be they Scale, Flyer or HiRail, so my locomotives are hardly maxed out.
