My: QBTS S=0.826 : CC 2025-01-17(DTE=371) K=1 Pr=0.36
--> CB=ND=0.4660 S0_PL=0.36 (77.25% m=4.80%) BEP=0.4660(-43.58%)
Ie. makes me 4.80% every month, totalling 77.25% at expiration in a year.

Calcs based on Sx = S at expiry, and CashAcct, not MarginAcct.
Of course result is lower if Sx < S.
And result is better if Sx > S, then MaxPL=0.5340(114.59% m=6.46%) for all Sx >= K.
BEP is OK, IMO.
Abbrev:
CC: CoveredCall
CB: CostBase
ND: NetDebit
S0_PL: PL @ Sx=S
BEP: BreakEvenPoint, ie. Sx
