HOer always has the advantage. Don't confuse the reasons for killing someone. If you killed someone after a HO it is because you were better and not because of the HO.
I offered to try it in the DA before and no one ever accepts.
Tests with someone better than me showed that the HOer had a small advantage over the guy trying to avoid.
Well ... in order for that test case to work ... you would have to fly like a 2-6 month noob ... seeing that you don't qualify ... no soup for you !!!
Most who start the HO spray from 1K to 800 out, couldn't find their arse with both hands when it comes to ACM, so yes, they do die within 1 to 2 turns 99% of the time.
There is a very finite amount of pilots that really have good ACM skills, and yes, they can go for the HO and if they miss, they can also end up winning the engagement ... the rest will die the majority of the time.
The next time you run into one of those "types" ... message me and I will go to the DA with him/her (if you can get them to) and prove the point.
