Hi there, my 2 cents:
Instead of doing the phases in weeks, build them into your week: 3 days low (but always above your BMR), then 1 day high (but not 3000kal, something like TDEE-20%) then 2 days low and 1 day high. ON your high days, change your macros to increase the carb intake. One day after the high-cal day, blast some large muscle group (legs or back).
Weight yourself only once per week, for example at the beginning of day 7. Your general idea was good, but the implementation was a bit off.
