Don't fly a Foxbat at 3 degree circuits. They will take forever at 50 kts on final (important if you are creating a bottleneck for others in the circuit and those waiting to take off) and you will not be able glide to the strip if the engine fails.
Unlike GA and other slippery aircraft, you will not gain speed if coming in steeper. The light weight and aerodynamics of a "brick" make that happen.
At 3 degrees, that would be "on the power" for sure.
Where I like it on final, is just sitting on 50 kts and the throttle just off idle. I don't know what angle that is and don't care. But it is far far greater than 3 or 5 degrees.
Being just off idle allows the option of increasing power or DECREASING power.....
Make sure lowest static idle on the ground is quite low( 1650/1700). 1800 static or higher and it will want to keep flying and will be difficult to get the power down on final.
This does make a significant difference. I'm getting about 2100/2200 rpm on final.
I generally use one stage of flap on takeoff and base/final. The main reason is that in a go-around situation I'm already set for flap.
Your widest circuits should be the maximum distance you can glide to the strip from circuit height. If any instructor told me otherwise, I would find a new instructor.

600 hrs on type.
The 22 is the Foxbat. The 32 is the Vixen......
