Is the 20251128 result different than your method?

Note: I remove GOOG when GOOGL is also present.

My screens in rank order:

        --PHL--    --RS--
1         WBD       PLTR
2         AVGO      AVGO
3         MU        WBD
4         LRCX      MU
5         GOOGL     LRCX
6         IDXX      GOOGL
7         AMAT      APP
8         KLAC      KLAC
9         EA        IDXX
10        CEG       ASML
11        AMD       AMD
12        APP       INTC
13        ASML      GILD

My script gets:
For top 7 commons
AVGO, WBD, MU, LRCX, GOOGL, idxx, pltr
Lower case ones are fillins after the stocks in common.
2 WBD
3 MU
4 LRCX
5 GOOGL
6 IDXX
7 PLTR
8 AMAT
9 APP
10 KLAC
11 EA
12 CEG
13 ASML
14 AMD
15 INTC
16 GILD

For top 3 commons
AVGO, WBD, mu, pltr, lrcx, googl, idxx
Lower case ones are fillins after the stocks in common.
2 WBD
3 MU
4 PLTR
5 LRCX
6 GOOGL
7 IDXX
8 AMAT
9 APP
10 KLAC
11 EA
12 CEG
13 ASML
14 AMD
15 INTC
16 GILD

Interesting how the order shifts depending on the actual number of stocks in common.

The final list, yours (from post) and mine (from script):

	Yours	My with top 3 
1	WBD	AVGO
2	AVGO	WBD
3	PLTR	MU
4	MU	PLTR
5	GOOGL	LRCX
6	LRCX	GOOGL
7	GOOG	IDXX
8	IDXX	AMAT
9	APP	APP
10	AMAT	KLAC
11	KLAC	EA
12	EA	CEG
13	REGN	ASML
14	INTC	AMD
15	MNST	INTC
16	ASML	GILD

For investing in the top 7 and omitting GOOG, the same stocks are picked. There are more differences near the bottom.

Based on just this one comparison, it would appear that this {OverlapsMin_N1Mo_N1HL} is a good enough backtest to validate my script's method of generating the overlap screen.

I do not believe the 32% CAGR, though.
