Whoa, your are progressing fast. Your are easily my senior now. Be warned, combat is the least effective activity in regards to money and Pilots Federation Rank. Seeing you progress, i was inspired to go up from deadly to elite at last. So, i searched for a compromised nav beacon to kill all those puny elite Eagles for "quick" upranking. So i found one in Hors and after all these years I learned, that an active crew member not only eats my credits but my experience points too (Amazing, you have never learned everything about ED). I am at 60% Deadly now, that means that i have only 800 ships to kill before becomming Elite (or 1600 if i use a crew member), sigh. At a compromised Nav Beacon that means 30 minutes work for 1% progress if i concentrate on small ships with deadly and elite ranking with 1 Million credits bounties.
Entertaining side story:
For some cash i interrupted my nav beacon hunting and accepted some missions. 3 headhunter jobs and 1 pirate hunt summing up to 10 Millions for 19 kills. So i went for the first victim, an elite corvette when a second target jumped in, another elite corvette. I dispached them both with still one ring shield strength. I decided to go after the third target (I equipped a size 7 prismatic shield
https://tinyurl.com/tagkrh7 so one ring is plenty shield and waiting for full shields takes an eternity). When I jumped into the pocket of the 3rd target it was another elite corvette, but no sweat. But then another ship jumped in. And, hey, guess what, a fourth elite corvette. A real challange at least. But in the end I had to run with the tail between my legs and 55% hull (resulting in an 859000 repair bill). So never get too overconfident, regardless how bored you are
