Hi! This is of course interesting data! I did a number of experiments, it was a few years ago now though, and I did not have any cool charts like you have.
However, I did note during my experiments:
-what was a good day, time etc one week, month, year, was different the next week, month, year
-even days seem unpredictable, my understanding to date, which never ends by the way tells me
-depends on competitors putting up similar stuff, or lack thereof
-may depend on the weather or other similar situations
-may depend on what sub-category you are listing items in!!
I firmly believe that someone selling collector plates will have different best times than someone selling coins vs someone selling hockey shirts vs something else etc. It even looked to me like someone selling coins in a before 1950 would see something different from one selling in after 1950 within the same main section!!!
I think you are doing the right thing, the only advice I have is that what times and days you see working now may not necessarily still work for you later in the fall. That is what happened during my experiments anyway.
Personally I stick with the same closing time (evening) and vary the days to the days that have traditionally worked best for me because it is expensive in terms of time and energy and relative sales results to be constantly running experiments only to find the same one differs so much from test to test.
Good luck and thankyou for sharing your information, I might yet try closing stuff during the timeframes you have there to see if it works in my categories!
Have a great day!
