Is it sometimes the correct choice to go over min cards in a runner deck?

You have a core of necessary cards. Cards that must be in your deck to answer what the corp throws at you. Breakers, plascrete, film critic, account siphon, inside job, whatever. Then you have a shell of economy+draw/search. Ways to efficiently get credits and core cards.

Prepaid Kate is strong because her core is so tiny. You want to start the game with as much economy shell as possible then get core cards later once the corp has threats that need answering. The ratio of core to shell is a good measure of a decks consistency. (Account siphon is so great because it's both shell and core).

So is it possibly worth it to improve your core to shell ratio by bloating your deck? I think if you have enough high quality shell cards then the answer might be yes which goes against most advice I've heard on deck building.
