I’m much more pitch-accurate in my head or mixed register than in chest. Is this typical?

I am a singer (classically trained, but culturally a singer of soul/gospel/r&b). I lead worship weekly on Sundays and have realized that I find it much easier to remain pitch accurate it my head voice than in chest.

Is this common? Is anyone able to share the science behind why?

(Ps. In classical music I am a low voice - I sing baritone, but in popular music I vary in range as a tenor, as gospel often has tenors in high vocal ranges, and I’m pretty comfortable there as long as my technique is appropriate)

Thank you!
