Tammy and I disagree on lots of issues here, so when we both concur on an answer, it means a lot. What she said is exactly right.
Now as far as "maximum" radiation, I am a living expert, with only 1 poster of 8770 members having had more than my 137 grays (GY). As with Kris, recurrences are often treated with salvage surgery. Extra radiation is an option if a 3rd recurrence would be catastrophic . The second round of radiation was very doable and gave me 4 NED years. I am witholding judgement on the wisdom of my decision to have those last 40 GY as 100 appears to be the maximum without major quality of life issues. But a second round now seems a walk in the park compared to the third.
You have many good options
