MOTIVATION
The BOP method has a major problem with setups (for corners) for a lot of cases. And also there is very less possibility to cancel moves.
METHOD
The Speffz lettering scheme is used here.
Buffer - I
Target - M
Allowed setups - <D B R>
Swapping algorithm - U' R U R' F' R U R' U' R' F R2 U' R'
ALL SETUPS
A: B' R'
B: B' R2
C: R2 B R'
D: Buffer
E: Jb from left
F: Buffer
G: D2 R2
H: D2 R
I: Buffer
J: R B' R2 (else you can also do this alg R' F R U R' U' R' F' R2 U' R' U2 R U2)
K: D R2
L: D R
M: Direct algorithm. No setups
N: R'
O: R2
P: R
Q: R B R'
R: B D' R2 (Or you can do U R' into y perm and reverse the setup)
S: D' R2
T: D' R
U: R' D' R
V: D R' D' R
W: B R'
X: B R2
COMPARISON WITH Other BLD methods (corners)
PARITY
If you get parity while using
i) Old pochmann - Do this any one of these algorithms after you finish edges
a) R2 F R U R U' R' F' R U2 R' U2 R U
b) U' R' U2 R U2 R' F R U R' U' R' F' R2
c) U' R' U2 R' D' R U' R' D R U R U' R' U' R
ii) M2 - Do this alg U' R' S2 R U R' U' M S' U S' r (If anyone can find a better alg please dm me I will add it here. Thank you)
iii) BOP - Same as old pochmann
EXAMPLE SOLVE
i) Old Pochmann
ii) M2
iii) BOP
CONCLUSION
Overall I think this modification is better than both OP and Standard BOP.

COMPARISON WITH Other BLD methods (corners)
| Method | Average Corner Swap Length | Average Setup moves and reversing them (including cancellations) | Average Moves per Corner |
| Basic OP | 15 | 2.2 | 17.2 |
| BOP | 14 | 4.1 | 18.1 |
| Modified BOP | 14 | 2.4 | 16.4 |
