Phal. inflorescence "staking"

[Lady Tottington]

Hi friends! A few years ago I was given a huge noid phal, which had two inflorescence that were quite tall, and now that it has begun blooming again, I notice that mine iare not nearly as tall as it was when I was given the plant. I'm sure there could be several reasons for this (lighting, environment, etc.?)

I wonder though if it could be also that I started "staking" my growing inflorescence spike to train it up? Or does that have nothing to do with it? When is it typically "proper" to begin staking the inflorescence if that's what you like to do? Also, I notice that my blooms are not as big as I remember it was when I originally got it as a gift, could this also be because growing conditions?

Thanks friends!
