I couldn't agree more
I quite like the idea of the top prize NOT being for the most spins, but for aiming at a certain position in the table. This position could change each month too.
This would introduce an element of strategy lacking in the current event, and would make it possible to OVERSHOOT, and then have no chance unless others make a similar miscalculation. Currently, it is a fight between me and sjn, and the current format does not seem to have produced any challengers under the "brute force" format of most spins.
Another idea is to use a different game, such as hands played in a card game. Choosing a game WITHOUT "autoplay" would also make quite a difference, even though minimum stakes might be offputting for some.
Classic Blackjack has no autoplay, and also has a low house edge, so players will not lose much, but will have to play every hand in person, a bit like the blackjack races held at Grief Club and 888 (when I played there).
Table Pokers are also an option, no autoplay there either.
For the longer timeframe, perhaps some kind of annual league could be introduced, with monthly results as usual, but some kind of annual prize table for achievment over the year, prizes just after Christmas, when we have just spent everything

An annual league would fit well with a strategy competition of reaching a position other than first, but not overshooting. Paying a prize, but also awarding league points for spot on, next nearest (either side), and so on.
I am sure a database for counting spins on slots could easily count hands on other games, since the records seem the same format under playcheck, transactions with a wager amount, and an outcome.
