Ah yeah i see. A roll skips you having to sort through character sheets introducing a silent pause in the narrative to determine whether a check passively succeeds.

I was a little confused by talk of character sheets because the players have them right there and they should be carbon copy with what the dm has.

I meant that for checks as the DM you can save time by relying on players who you can trust to know the game and be honest, rolled or passive. I argue that a DM that asks for my stats has not yet been any less immersive for me. It takes a split second and I'll take it over railroading every time.
