I liked it more as a side tool for risk management than as something to follow blindly. Trade control feels cleaner, and the final decision still feels like it belongs to the trader. Starting light makes the result less emotional.

This is easier to judge on H1. A sample of 20 setups with BE after 1R gives a cleaner read than one good result.

Better to treat it as a side filter for risk management. A 31 setup check on London open can show whether it improves the actual trade routine.
