4x4 Obli Method (Petrus Yau Variant)

Do you have speedsolve video using this method? Tried one solve with this but seemed to be way too hard to look ahead.
 
Many years ago (like, 2009?) I used to do a 3×3×3 block first, just as in this method. Something you can also try is to use keyhole to insert wings or the corner into the block, sort of like this:

/* Scramble */
B2 R2 B2 F2 D' L2 U2 B2 L B' R' D' R B2 R D' L D2 U Fw2 L Uw2 F Rw2 Fw2 B2 L Fw2 B' Rw2 L2 D' R Uw L2 Fw2 L' Fw Uw' F' Rw D L Fw'

/* Solve */
B' r' F r F r f2 D f2 F u2 R' u' L2 u' // three centres
F r2 U R U' r2 F2 L2 u' R' u // two edge pairs
F D2 B' U F' u2 // almost block
R U' R' U' u2 // finish block with keyhole insert

Cool concept, I have done an average of 5, and got a 58 average with a 54 single (DP), seems somewhat viable as a speedsolving method, sub 40 is definitely possible
