Whirlflock is Carrageenan and Dispersant (the part that makes it Whirl- not just flock) so when people weigh one that's worth remembering, I always use a 1 whole tablet in ~25 L wort. Good rule of thumb would be if you doubled the gravity to double the dose.
That said its really far too complicated to be precise (not just for home brewers) all advised doses come with a caveat to determine exact doses by in house trials, fine if you're doing the same beer over and over again.
This is a very worthwhile read View attachment 41737 and there is some very good stuff here at the IBD (the wort boiling sections are relevant).
