This is seperated into 2 posts and 4 points.Its essentially an analgram of all my hyperspace work.Some of it had already been done by others{Hyperdrive and gravitational influences}.
1.Hyperdrive speed
From the "Incredible Worlds of Star Wars Episode 1",the approximate distance from Tatooine to Coruscant can be found.Its is 52,000 ly.Using an approximate travelling time of 20 hours,that yields 2,700 ly/hour.
Note,Darth Maul Journal short considerably shorten this estimate,considering the attacks of the sandpeople.
E1701 contests that Maul was not on Coruscant.This is not true.Research done to show Darth Sidious was Palpatine indicates otherwise.One of their methods was to actually compare background images of Darth Sidious meeting with Maul and Palpatine meeting with Amidala in which the same props/background shots were found.Considering that Amidala meeting was on Coruscant,thus,Maul meeting was on Coruscant.

2.Navcomp
Some people think that the navcomp functions by bringing up navigational data and the approiate jump routes,then modify it to suit the purposes and jump.Many have even gone to the extreme of the navcomp merely being the database of possible hyperspace jumps.
This is not the case.In TESB novelisation,Luke revealed that Dagobah was not on the navigational charts R2D2 had.
Assuming he didn't venture off to some cartographical mission to locate Dagobah{unlikely},what this probably meant was that no known jump routes to Dagobah exists in R2D2 charts.Thus,Luke navcomp in effect,created its own route to Dagobah.
An alternative lies in there being a hyperspace beacon at the Dagobah system to guide Luke in.However,as Dagobah is an uninhabitated planet,this is unlikely.
Its is possible that Luke found the planet through the Force,similar to how previous Jedi found planets teeming with Adegan crystals.
Nonetheless,a jump was executed to the Dagobah system,without the jump route being found in their charts.
3.Gravitational wells and hyperdrive
The presence of a gravitational well does not mean a jump is impossible.

We're still within the gravitational influence of Tatooine," came the cool response. "It will be a few minutes yet before the navigation computer can compensate and effect an accurate jump. I could override its decision, but the hyperdrive would likely shred itself. That would give me a nice hold full of scrap metal in addition to you four."

So,how does an interdictor cruiser work?
First,we need an explaination on mass shadows.There are several assumptions that we have to either discard or follow.
1.Mass shadows are created by gravity wells.
2.Mass shadows create gravity wells.
3.Mass shadows exist in the same region of space curved by a strong gravity well.
We're not going to debate the specific nature of a mass shadow,as in whether or not its an object intrusion into hyperspace etc.
Despite of the above 3 assumptions,we do know this.Travelling near or into a mass shadow is dangerous.Observed and described effects either involving the ship being permantly lost in hyperspace{torn to bits} or experiencing severe hull stress,damaging the ship{Dark Force Rising.Karrde accident}
Furthermore,we learn from the Dark Fleet Crisis series that improperly tuned ships may be destroyed by the exit forces of entering or exiting hyperspace{specific quotes may be found in CX
http://www.theforce.net/swtc}
I thus theorise this.We know that some force acts on the ship when near or in a mass shadow,as the ship experiences stress or even deformation.We know that if a ship is not properly tuned,stray forces can kill its occupants.
If mass shadows,or gravity wells,{depending on which assumption you use} exerts forces on the ship{as we seen},then,the problem of jumping in a gravitational well is solved!
The presence of a gravity well or a mass shadow inserts additional forces acting on a ship entering,traveling in or exiting hyperspace.If the ship is unable to deal with this force,either in terms of it being unplanned for or the magnitude overriding its safety equipment,then the ship can and will be fatally damaged.
As such,the presence of a gravity well or known mass shadow introduces new factors into calculating a hyperspace jump.The navi-computer must now factor the forces acting on the ship in,to prevent the ship from being destroyed.
An interdictor cruiser will then work in this manner.It doesn't prohibit hyperspace travel by creating a gravity well,it prohibits hyperspace travel by simply fluctating the various conditions a nav computer must deal with.By rapidly changing the orientation and magnitude of its gravitational wells,a nav computer cannot factor and sense everything it requires for a jump!
However,to pull a ship out of hyperspace would not require such an apparatus.What will be required is an unexpected gravitational field,large and powerful enough to register on any sensors the ship have and trip the alarms,shutting the hyperdrive down.
