Do you take into account the dose calculation algorithm used when selecting a prescription dose?

I was asked to forge an answer for this one and it’s a little beyond my knowledge base so I queried a colleague here and am enclosing his very excellent response. The physicist who wrote this (who wanted to remain nameless, so lets call him MedPhys NOS) has spent a fair bit of time working on these ...

One additional point to consider: lung tumors have most commonly been treated using 6 MV energy because the buildup effect at the lung-tumor interface is less prominent at lower energies, but perhaps more importantly because dose calculation algorithms have generally been less accurate at modeling d...
