I like dual pattern in that case. split patterns still work well, but really no need

Sorry to be so uneducated lol
But I thought split and dual where the same?
I thought it was single ie 272/272dur 454/454 lift
And dual or split ie 276/288dur 420/444 lift etc.
Are dual and split patterns different?
