Why is the D point projection of your Gartley an 0.886 rather than a 0.786 retracement? Also it’s best to have an 1.272 or 1.618 ABA fib extension that converges along with your 0.786 at the PRZ D point.
The black level is the ab=cd measurement. the PRZ is the zone between ab=cd and 0.786XA. according to harmonic rules the Gartley is not completed until Terminal Price Bar tests the last level of the PRZ. Consequently, the D-point (completion point) should be placed at the last level.
What is best for you, doesn't mean best for anybody else. If you insist that 1.272AB/1.618AB extention is the best for everyone then you need to provide you backtest results. 1.272AB, 1.618AB ratios are commonly used with advanced formations. A Gartley Pattern is NOT A Gartley Advanced Formation(1.272AB/0.786XA). The first one is harmonic, the second one is not. Same with a Bat Pattern and a Bat Advanced Formation(1.618AB/0.886XA).
