While I haven't used Eliminator yet, I regularly exceeded your rather understandably conservative recommendations already in most of my Post war units
(And I melted 1.5-to-two pellets at a time most of my childhood too. Like drop numbers in modern locos, I feel it depends on the unit
)
While smaller, all my PW pellet reservoirs hold that much even with the packing full of "gunk" on a few. I.e. almost a solid block of gunk.
Though fluid, they don't really hold much, in fact I know of no loco that takes less than the Generals and they even get 4 drops
