If the Terrans invented Jump drive in 2087, and the T5 Current year is 1105 again, we've got 5626-2087, or 3541 years. At J-1, travelling a Parsec every week, and returning, we have star and planet "cursory scan" data for 25 parsecs out from colonies with maintenance ports. But once they took over the Vlani empire, those planets would be their outward bases, so out from the Vilani border starting in -2204, and by then using J-3 (TL12 in -2250), so 78 Pc out. I would assume colonies organized by terrans would push out an average of 1 parsec a year - but it could be "wild wave" periodically, with ships going out at best jump until they would need maintenance, call it 150 pc; but then they'd need time to build up to have a Class "B" starport, which might take 100 years on a garden world. Each time a better jump drive is invented, that rate of expansion improves, as we would expect that discovery to permeate human space as fast as possible.
J3 period during Rule of Man: -2204 to -1776; 428 years, 642 pc. That's 15 SECTORS off the Vilani Imperial border
Seeing as the collapse of the Rule of Man is not going to significantly affect people hundreds of parsecs away, we'd be looking at this continuing until the invention of J-4, which was likely around -1700 in most of these fringe empires.
So, for ease, let's do the J3 era as -2200 to -1700, 500 years, 750 pc.
Now the J4 era is another 1000 years, -1700 to -700, 2000 pc, or 2750 total out from the Vilani imperial border.
TL14/J5 era is probably 1500 years, -700 to current 1100; AHL puts the Imperium at TL15 around 1000. Let's just use that, 1700 years, 4250 pc, 7000 parsecs total, and scouting at J5 being 125 pc further out from that.
The IISS probably would NOT have all that data, the question then becomes how far out the IISS can establish bases for maintenance to determine their knowledge base. But wherever they go, it is almost certain they encounter high tech humans.
