I do wish people would stop propagating this. First, you don't have to do it at 7 seconds, it is possible to do it at 6 or 5 seconds. Secondly, you don't save any time, you just think you do. Thirdly, why are you in so much of a rush that you're trying to min/max supercruise? Honestly, just relax and enjoy the game .... plus if you're going as fast as you can and you get interdicted, you have to lower your throttle anyway to help with the tug-of-war, why not just set your throttle in the blue zone anyway?
Hiya pal, not having a personal pop at you, just dispelling a few misconceptions you have been propagating...
Supercruise agility is hardbaked into the ships parameters and has nothing to do with the thrusters, FAD or modifications to either, its why the Federal Gunship is more agile in supercruise than it is in real space.
RE the 7/6/5 seconds blue zone "trope", it is possible to drop it into the blue at even 4 seconds if you are super Jedi-Using-The-Force quick. However, if we are having to tell someone about "the 7 seconds rule", they are generally a more novice pilot, typically making loops of shame on a regular basis, so need, or at least benefit from the extra time window offered by doing it at 7 seconds.
On the point of your preferred style of supercruising all the way in the blue zone, yes, it is a valid option, but even you admit it takes longer, and given the undercurrent of people bemoaning travel times, vanguarded by Obsidian Ant, I'd advise against telling noobs to fly in the blue zone all the way. Teaching to use blue all the way and making their travel times a lot longer than necessary would serve to pour gasoline on the fires the instant travel campaigners are lighting every so often, and if enough noobs got bit by the bumbling in the blue advice, their voices added to the current instant travel campaigners lobbying might tip the balance and be enough to persuade Frontier to add some tripe like intra system jumps instead of supercruise.
I don't think either of us want to see supercruise removed because too many people say its boring, so would you mind working with me a little? In future threads like this, we can both say that supercruise using gravity braking is the fastest method of reaching your destination, closely followed by 7/6/5 second rule, however a more relaxed but slower alternative is to simply fly the complete journey in the blue, which is the pace that supercruise assist travels at, so the ultimate relaxed supercruise method is supercruise assist.
