An observation about the maths.=20

> A speed of Tan[=CE=B8/4]=C2=B74/3 has the radius precisely correct at the=
 midpoint

If =CE=B8 =3D 90=C2=B0, then the speed is Tan[22=C2=BD=C2=B0]=C2=B74/3 =3D=
=C2=A0(=E2=88=9A2=C2=A0=E2=88=92=C2=A01)=C2=B74/3 =E2=89=88=C2=A00.55228474=
983, which is only an edge bigger than Adobe=E2=80=99s fixed value of 0.552=
