investing is more than just a buy or sell. what about position sizing? what about position risk? portfolio risk? portfolio beta? how do you benchmark? what kind of drawdown do you incur? what's your sharpe ratio? why are you not adjusting returns for at least the market, and moreso common factor returns?
rank(total_return) != investing success
Your "metrics" should be educational and make people more aware of the financial decisions they are making. By boiling it down to buy/sell recommendations, you make investing into gambling with a 50% chance of being right.
your "transparent" ranking algorithm is not disclosed anywhere - do you have any documentation that your algorithm does more than just show who made the most "money" historically? (past performance is not indicative of future performance!) are your rankings stable? how do you identify persistence?

If the sector is big because it has a lot of medium/small sized constituents you gain from this implementation because a cap weighted index would under allocate to these smaller names.

In this case, the equal weighting is abstracted away by 1 layer - each ETF is already cap weighted, so you aren't getting the full effect of equal weighting. Instead, you're reallocating to the ETF that has underperformed relative to all others, so as already pointed out, you are betting on reversion rather than momentum.

Imagine what we could accomplish if capital/compute/mindpower resources were reallocated from showing me ads to solving something I cared about. Can we not have another cab/delivery/ad/food delivery/message/social text/video/short video/music network?
My deepest condolences to the Meyer family, I can't begin to fathom the pain and loss you must feel.
