I have seen references to the circle's SNIP:
In the Western Desert in WW2 Hans Marseille solved the Lufberry Circle
problem by high angle deflection shooting at minimum range - knocking
down serial kills of Hurricanes and P40s daily. The 'circlers' were
essentially helpless against this tactic when used by an opponent of
superior energy capability. Note that with more or less equal aircraft
(and more aircraft available to join the fight) the Circle isn't that
successful. It's also a way to get 'anchored' over enemy territory -
when the fuel level rate of drop becomes an item of interest. The
Circle worked well against conventional curve of pursuit attacks aince
an attacker necessarily flew in front of the preceding defender,
unless attacker had a much higher rate of knots so he could get in and
get out before said second defender could get guns on him. Nowadays
missiles defeat the defensive circle.

Right on!

Lufberry's looked good on paper....that is until the circle was engaged by
fighters with lower wing loadings; and flown by pilots who knew how to bleed
down and arc. Snap shooters like Marseille could play dixie on these
circles...and did just that...against poorly flown Lufberry's. In fact, even
a higher wing loaded fighter could engage through low yo yo's and arcing if
flown by superior pilots. This was the "real" learning period in ACM. It
involved the painful transition from thinking defensive to thinking like a
Hans Marseille......attack! Just like Hartmann, he boresighted for
conversion range using the windshield bow for wingspan instead of using the
sight, then he pulled g for lead; raised the nose in the turn for gravity
drop; centered the ball for trajectory shift, and hosed them at high angle
off before he bled down and out of the cone.
Pilots who were thinking about things like Lufberry's as they entered the
war didn't last very long in combat. Nothing kills a fighter pilot faster
than over thinking the defensive side of the ACM equation.
