How did nitrous get such a bad rep...?

Just for the heck of it if I ever tear my 422 down I want to try to check a couple of rings to see what my ring gaps are after 4 years of bracket racing and running alcohol. The best pass ever was a 5.98 in 2018. My last pass in in 2019 was 6.04 so after four years the car never lost anything. The ring gap had to open up during that time. Just curious to see how much.
When I talked to the machine shop that built my engine about nitrous one of the first questions was how many miles are on the engine??.. I don't have a clue...
Besides the actual break in.. I went mostly drag racing for the first three years.. then mostly cruising and some drag racing in the last couple of years...
The most important part was my plan didn't raise any red flags...
When I talked to my cam grinder (Ken at Oregon cam grinding) he said my current cam wouldn't take advantage of the nitrous as good as it could.. but still no red flags he seen in my plan..
Both said it sounds like fun...
