I just got back after a 10 month+ trip.
1.6 mill ly and 70k+ systems. That's by-the-by, but I thought I'd give you some stats & info I got out of it.
It takes 45 secs per jump MINIMUM just honking the system and going to the next one. Add in fuel scoopping (I used an Asp with 6B fuel scoop) and plotting next 1k jump, you can expect a maximum of 1 jump per minute if you don't scan any bodies. Anything else you do on top of that will naturally reduce the quantity of systems you can do in a given timespan. Scanning profitable bodies only, scooping, plotting new 1k courses, I averaged somewhere around 40 to 50 systems per hour. If your game time is limited, you may want to use "45 jumps per hour" to calculate your time arriving back. You can get 80 per hour if you use economic route and don't fuel scoop or scan anything. You will discover your own rhythm, so don't get bogged down in trying too hard.
For scanning, I only scanned Water, Ammonia and Earth-Like Worlds within systems, apart from a few random others along the way. I scanned Neutron Stars and Black Holes when I found them - planned or by accident - but Neutrons have changed since 2.2 so you may want to skip those if you feel the risk is too great on a long haul trip. I scanned all mine pre 2.2 and, because I was carrying nearly 1.5 billion credits of data, I stopped targetting them. Good CR though. 40k CR and + 50% if you are first discoverer at roughly 60 per hour can be quite profitable.
I generally never went after anything over 2k ls away - which is about 2 minutes travel and scan time. It depended on my mood and how profitable it would be whether I went any further. Eg, travelling 30k ls to get 4 Water Worlds.
Heat. It is your enemy. Be careful. It is an enemy that comes a close second to stupidity. Stupidity and heat are the only things that can cause you harm out there. I managed to get back with 81% hull.
Trying to get your fuel scoop to max every time is not necessary and can lead to heat issues if you aren't careful. On a 752 fuel scoop, I generally went for max of 740. Scooping every star vs scooping when tank drained is slighly slower. Always leave 1 jump in your tanks for emergecies. My Asp could do 7 max jumps, so I scooped every 6 when I could. Trying to max your fuel scoop every time is unwise.
Fastest route will cover more distance, of course , but will require more fuel scoops along the way - economic routes can sometimes cover 200+ systems and no need to fuel scoop along the way.
In the same amount of game time, you can either scan lots of bodies and do that in fewer systems or scan only selected and profitable bodies in systems and do more systems. Scanning 30 moons in a system over, say 25 minutes is time not well spent. The CR is very low for moons and in the same time you could have jumped to 20+ more systems and found profitable bodies to scan in those systems.
I averaged nearly 22k CR per system in my run. About 925 CR per ly. Here's a link to a post with the spreadsheet of my journey if it helps you.
