Could you tell us what's the "one other method" ?

Have you ever heard of a manufacturer actually held liable for that ?

Anyway, this is not a case of "right" vs "wrong" deco but rather a continuous
scale of increased *risk* of DCS. Different profiles will expose you to risks
of 1%, 5%, 10% ... based on a general statistical group.
Now the amount of risk you consider acceptable for yourself is of course your
own business, according to your kind of diving and the support you can get.

Manufacturers should print that risk level on the box, or at least
in the documentation. The trade-off here is obvious: people want a "safe" 
device, but divecomps that are too conservative don't sell well. Word
spreads that divecomp "XYZ" nails you forever at 3m, and that's it.

May be an adjustable risk factor is what you are asking for ?
   "Well, I feel great today, let's try 15% ",
   "Uh ? Then I'll go for 20, 'cause I ain't no <insert favorite personal
reference here>"
