Active sonar, useful for anything other than basic ranging?

Won't the torpedo home in on me more easily if I am at high speed ?

I deploy the Nixie and try to "creep" away at a short sprint n long drift or 4kts

No no.
Dropping an active sonobuoy will give you the EXACT POSITION of the torpedo and you can update the position in real time and watch the result on the navmap. So you know precisley where the torpedo is (and thereforse the dstance to your frigate) and where it is going.
Just choose a course that opens the distance at max speed and continue to look at the navmap. If the torpedo follows you simply change again direction and drop if necessary another active sonobuoy. If the torpedo is going strait for you drop the nixie.
But going at 4 knots without knowing what the hell the torpedo is doing is NOT A GOOD TACTIC.
Use the strenghs of the platform you're on.
You have tens of sonobuoys for a reason on the frigate.
Use them, they are not there just to be pretty. They are usefull in situations like this one.

Torpedos can be of 3 types : wake hommers, wireguided and fire and forget (such as those launched by the frigate). If you're attacked by a russian skipper most probably the torpedo will be a wake hommer. You can evade a wakehommer by getting out of its way before it intersects your wake (and getting a fix on the torpedo helps you so you see that an active sonobuoys is usefull). If the wakehommers continues to creep on you drop the nixie. If it doesn't work go to 3 knots and wait.
For wireguided torpedos, you can't have the luxury of going at 4 knots, so drop active sonobuoys, watch the navmap and evade at 30 knots changing course every 2-3 minutes.
For fire and forget torpedos, drop active sonobuoy. Look at position and get out of the way.
Of course in real mission you can't know beforehand what type of torpedo is coming your way so the best tactic is : drop active sonobuoy, update in real time position of torpedo and evade changeing course at 30 knots until the torpedo is far away from your position.

Thanks, you were a big help to me. I was doing this all wrong

I hope you don't try that with the latest version of LWAMI...
