Marx had a fun thread some time ago. He had a screenshot of a system map, highlighted a planet and asked: what type of planet is this? There were many different answers. And I must say with 50.000 system maps under my belt, I couldn't tell you with certainty)
I remember that many people got it wrong, or got it only because they gave more than one answer, even though I asked for only one (precisely because of this). However, I can't for the life of me seem to be able to find that thread now, neither via this forum's search nor Google. How odd. (It would help if I remembered the exact name of the thread though.)
And yeah, I don't think anyone would mind it if you couldn't select stuff on the system map until you scanned it with the FSS.
As for targetting stuff, turning your ship to it and then FSS-ing it: sounds good in theory, but in practice, moving the FSS's turret view is faster than the supercruise handling of any ship. Unless your input method's sensitivity is set too low, of course.
If I were to actually travel to a virgin system & find an earth-like or terraformable the simple travel time to get there & back would render any meaningful Cr/Hr calculation meaningless.
Funnily enough, I did exactly that calculation way back when, to compare the profitability of various exploration "styles". The highest was neutron star farming, the second was going through systems and just honking, the third was flying to valuable planets you find and scanning them. How do you calculate Cr / h for these? Simple: you take the average (or median) distance ELWs were in systems (we didn't have nearly as much data then to look at WWTC data separately, so I just assumed that they will be around the same distance, what with the habitable zone), estimate how much time supercruising there would take (thanks to the fuel rats, we have lots of data on that), and there you go.
Of course, Cr / h would have been higher with the FSS even if Frontier gave the old ADS+DSS scan values to the DSS mapping now, what with flying no longer being required. They decided to give the old values to only the FSS's infinite range scan though, and ratcheted up the payouts for flying, so the new values would be much higher.
In
this thread, we eventually got a figure of 41 million Cr / h from Allitnil, and that was using pre-discovered ELWs of his (ELWs you discovered before Chapter Four but only mapped now actually pay out more than if you find an entirely undiscovered one) plus the LYR bonus. I don't think you can go much higher than that via exploration.
Also,
Remember, the ADS provided no more from the honk than the FSS does (in terms of credits). Perhaps a tiny bit more in as much as you could spot an unusually colored gas giant, but the trade off in accuracy for most bodies identified by both makes the FSS a clear winner.
Just to make sure, in terms of credits, the FSS provides more per honk than the ADS did. As mentioned before in the thread, the developers originally planned to strike credits from honking only, but then changed their minds, and the way they implemented things, for the simple act of honking and moving on without scanning anything, you get more credits now than before Chapter Four.
This isn't only from the auto-scanned stars (not exactly high value), but also from adding a bonus to the main star depending on how many and what kind of bodies are present.
Oh, I never said it wasn't a time sink. I agree that it is a time sink, in fact I agreed with you on that issue, but as you also pointed out, time sinks aren't necessarily bad.
Not necessarily bad, no. But they are rarely done well either (largely thanks to many time sinks used in MMOs, to get people to spend more time playing in any way reasonably possible), and the FSS wasn't designed and implemented very well either.
Clearly, I consider five seconds to be way too short for exploration to be fun. On the other hand, a maximum fifteen seconds, simply to get enough information to decide if a system is interesting enough for me to take a closer look isn't.
Fifteen seconds was also the old time for honking, calling up the system map (= not instant!) and looking it over to see if there might be anything of interest. It was fairly well accepted when calculating time that in a hurry, you could do 45 seconds in systems minimum if you're in a rush, or 1 minute if you account for actually exploring too.
I always wondered though why Frontier didn't change the honk to be faster now, if time was now suddenly much more important in Chapter Four. But it's probably only because they didn't want to change the sound.
