Phal Spikes: To Cut of Not...

[zxyqu]

Ok, before you all harass me about posting this question... I'm a scientist, and this is how I think, sorry. But does anyone know of any studies that have been done on Phals that compare the benefits/problems with cutting the spike versus leaving it on for more blooms. I can see the benefits of both, hoping for a few extra buds from a beautiful phal, or boosting the plant a little for the next spike, maybe 2 this time.
Anyone have a percentage of success on getting a secondary spike when you dont cut, or having compared cutting of one to not cutting another similar one?
If noone has compared them, I was hoping to propose a project, or more of an experiment, comparing a couple identical, or as close as possible, phals, cutting some and not cutting others and comparing the next round of blooms. The results would obviously be affected by growing medium/watering/fertilizer/weather/on/on/on, but I think it would shed some needed light on this oft asked question. What say you OB, worth it or not?
