You should ask your instructor. I'm not an instructor, but...

I think you're looking at this the wrong way. The point of the ground
reference maneuver is for you to manipulate the plane's attitude in what
ever way is necessary to achieve the desired ground track. To follow
a circular ground track, for example, the bank angle will depend on the
ground speed, which may change as you progress around the circle (due to
wind).

Just piling on. The goal of "turns around a point" is to describe a circle
of constant radius around a point/pylon/tree/whatever. If there is any wind
at all, the bank angle will be changing as you move from upwind to downwind.
Max allowable bank is 45 degrees, according to the Airplane Flying
Handbook...which, I suspect, you have never read. It describes in great
detail just how this maneuver (and others) are to be performed.....

That was my thinking too. Trim the plane for
level flight at your normal pattern speed. Fly
"airline pilot" turns as my instructor calls them
and use minor elevator and throttle changes to
maintain constant speed and altitude. The turns
should sort themselves out if you do this.
