Don't forget, the aggressor has to have a wake scanner fitted first.
Not many PvPers will give up a precious shield booster for that.
Then they have to scan it. In all likelihood, you would have reached your exit point by then.
Then they have to charge they FSD and jump. By this point, your cooldown will be done, and you could have either dropped out of SC, or get ready to jump again.
If you do jump again. And they catch a sniff of your wake, then the chase is on - this is known as gameplay.
Dropping out of SC after the jump, then performing a "stealth jump" is almost 100% guaranteed win.
I still like the idea - with limitations of course. Maybe just a maximum of 50% of the jump range again.
