I had 66Gy (33 sessions). I asked why and they said that 66 was right for my situation, but I met (older) guys in the waiting room who were having more. My PSA has gone below 0.1 so 66 seems to have been enough.
I note that I was getting 2gy each day compared to your 1.8gy, which seems to be another inconsistency. I asked how they picked the daily dose as well, and asked why RT was not delecvered in say 11 sessions of 6Gy, or even 22 session sof 3gy and here they too mentioned the "kill the cancer, but not the patient" message.
They said the total and daily doses are calculated on the basis of what has been learned while giving RT to the patients treated in the decades before it was my turn. (They did not say what the old doses were, but I beleive that at the beginning of RT people were given many more Gy.)
As for SE, I hope you avoid as much as possible.
