No, Back in the olden days it was correct your theory that 10liters for ever 1KG this is so that within the wash time you got a clean result.
However nowadays manufacturers can add an extra 1KG or 1.5KG to the 60l drum for instance, so washing 7.5KG. this is because as the future has moved on, more laws have came in that heaters must be energy efficient and all machines must be A wash performance etc, so Manufacturers increase the rated capacity and extend the wash time, they increase spin lengths and use different rinsing techniques.
Plus in a Bosch Logixx 8 you can fit an 8KG load of t-shirts (40) in the drum, and still have slight movement between (thats 65l). The duration of the wash is quite long at 2:20 but at the end the machine has washed and rinsed pretty well, much better in fact than old machines which only hold less washing.
In fact manufacturers also realised people always overloaded their machines - in fact I quite regularly stuff 8KG in my Hotpoint WM31 - it fits, machine motor copes, just very little movement - manufacturers decided that as people overload, we'll increase the capacity in the same size drum, and then use different motor, that way less breakdown (from motor) that's why some come with 10 year guarantees to try sell the machine.
Only washer fans know that they aren't using stated capacity drums, but general public don't care, so long as it cleans, has a 40 wash and has a short programme/option. Infact no-one has ever written on review size, the clothes don't all fit in the drum, because no one would care if that was the case.
I agree that 11KG cant fit in a 71l drum (like Hotpoint claim) or 12kG fits in a 74l drum (like Samsung Claim) - they are just marketing campaigns, but smaller capacity is correct.
Thats my opinion, but I believe you older* people that think 10l in 1Kg need to move on a little, no manufacturer (Not even Miele) gives 10 litres into 1KG on a home machine.
*No offence to be taken, and completely my own judgement, modern technology is here now, not a timer dial that clicks as it moves.
