depends on your ship and on the situation.
If you run, it's for something, is not because you heard about sprint-drift you should use it all the time
some examples :
If the target come to you, of course you don't need any sprint, EXCEPT if you want to refine the interception point.
If you must reach a distant position quite quickly, HERE you will need sprint&drift.
But NEVER kill your stealth when you don't need to.
And never go to max speed : just look at the Db charts and understand this=> each more 3 Db your sound is doubled.
After this is just a matter of calculation of the time you need to reach the desired point.
Usually, with nukes, 20 knts is a good sprint speed, still quite quiet, and fast.
But when you drift, NEVER order to stop, as said Kapitain ...
Or your TA will fall in deep water and you will have an AWFULL TMA.
Of course, people using AC TMA can't see this, as AC will always manage to give you a good and very fast TMA whatever you do.
That's why lots of people consider TMA is very hard, if they try manual, when it is not.
Just because they don't know they have to take A LOT of care about positionning their ship and using right speeds.
Manual TMA force you to drive your ship as a real one, considering speed and attitude of the ship, when AC let you do whatever you want with your ship without feeling the counterpart of it.
In any case, if you want to make a manual TMA on a target, NEVER go under 7 knts.
So you can say, on sprint and drift, you speed will be beetween 7 knts and 20 knts (more than 20 only if you really need it -in case you are late on spot- but never under 7 knts).
The best thing to do, to cover the maximum of the area in the minimum of time with your sensor, is to do this =>
going 20 knts for 4 minutes, then changing course for good listening position, still at 20 knts for 1 mn, and then slow down.
This way, your TA will be aligned in the right direction to listen for contacts (or very close to be) when you will slow down.
With Akula (at this time) you need to slow down to 7knts to have the best detection capabilities, above, even at 8 knts, you lost detection capacities and under, you lost TMA accuracy, so 7 knts is THE speed to detect and to make the TMA with the Akula.
Not 6 or 8, 7knts.
For US subs, this vary from 7knts to 14knts for the 688i and from 7knts to 15knts for Seawolf.
You are still very quiet at these speeds.

Oh, and last thing, between the end of drift and a new sprint do I have to change course ?

of course yes : if you sprint, thats ONLY because you needed it, so this mean you speed up in the direction of the contact or supposed contact.
So, when you slow down, you need to go at least 35° to the left or right to detect the contact on your TA, as described above.
But you will need to see if there is any contact in your new blank area ...
You know Goldorak, it is not because you hear about a tactic you must use it. It depends on situation, and you must ask yourself "WHY should I do this".
If you do that, you will understand much better how to use it.
