yes this is true, and if you knew in advance that at least 2 chronos would spawn, a third is not more suspicious.
however, seeing 3 when 1 or 2 were not predetermined does make them more suspicious, as 3 chronos is an unlikely event.
out of all the ways a setup can roll, many more of them have 2 chronos than 3. this makes it more likely that at least one of them is faking.
this is of course assuming it is random chance, aka not arbitrary odds, and that no other infromation is affecting this
however an important bit is that the effect this third chrono has is the same across the group that is, if two chronos just claimed, and then a third one claimed they should all be equally suspicious.
however this holds true to some complications. say that the first 2 chronos are fully confirmed somehow (as in, truly 100% confirmed, there is no way even theoretically that they could be faking), then the added suspicion the third gets is still the same. since the other two are fully confirmed, that makes that added suspicion 0 (or at least it should be 0), making this new third chrono no less suspicious than if neither of the first two ever even claimed.
In situations such as these, order and simultaneity/universality (theres a word that combines those two i just cant put my finger on it) of information usually plays a significant role
its like, if you flip two coins and they land heads, the last one is still just as likely to land heads as it is tails, but its still more likely to flip 2 heads than it is to flip all 3 heads. if you already see two and know they’re heads, than the third is 50/50, but the event of all 3 is still 1 in 8 (versus the 1 in 4 of flipping 2 heads)
