Excellent @Kalkulus ! I think it's a great post.

In the wild format it is evident that these peaks must correspond to certain bot algorithms. Not necessarily all accounts that send teams at that time are bots, but it is an abnormality and therefore suspicious of being bots.

In the modern format there are no obvious peaks, except for clusters 4 and 5, where
They are clearly observed when time is ending. To me, this behavior is quite suggestive, and I assume that it is most likely bot algorithms.

It is my opinion, therefore far from being a fact, bots that cheat are located in this zone where time is running out. If you read my post: At last! The best Splinterlands update in a long time that closed a backdoor published several months ago you will understand what I mean. Now what I haven't understood is why Splinterlands now automatically sends teams before the time runs out, it's like they want to give those algorithms another chance.

In any case, if it is the use of bots in modern, which violates the TOS, it is very likely that those spikes will begin to dilute along the timeline. That is, it is very likely that they decide to randomly alter the times in which they send their teams. But, that would be a clear demonstration that the spikes do correspond to bots, and a validation of your analysis methodology.

If you continue with your detective work you have the advantage that everything has been recorded in stone, well on the blockchain. Therefore, you can analyze how many accounts have been sending teams at exactly the same delta time. It would be interesting to see if they are always the same accounts, which makes them very good candidates to be considered bot users. Although, this is not necessarily proof, it is an important element.

Again, congratulations for an excellent post and for keeping Splinterlands part of my interests and entertainment.

Greetings...
