Supplementary Note: The 5.* versions before wp5.8 did not show pathlength reduction
@bcworkz Thank you very much for your answer.
Sorry, but I made a mistake. It is found that the number of codes for each transaction of the latest version of wp has been greatly reduced：
pathlength Variation：
WP5.9 is reduced by 18.7% compared to WP5.8
WP6.1 is reduced by 25.2% compared to WP5.8
Did you make some changes, such as: remove redundant and useless code, optimize code logic, etc？
Thank you for your time.
