yeah… like “a house” vs. “an honor” It’s easy: the +n is a binding sound to avoid a hard stop between two words when the first ends in a vowel and the second begins with one. A hard stop only applies to spoken language, so the +n should be applied where the spoken next sound is a vowel.
For example: “A “large hadron collider”-like setup”, vs. “An LHC-like setup”
We’re past what 1984 could even imagine.
