it's obvious, so nothing surprising.

Also not all double spends are an attempt to fraud. Many people are just curious to see in action how double spend attempts are treated by the network and/or try to build systems that deal with unconfirmed transactions.

use bartail on debuglog of a bitcoin core node ...  and you see a lot more double-spend attempt per hour.

No, this is really a very small amount. It is a very small percentage of the total transactions.

I would also assume that many/most/potentially off of these double spends are not actual double spend "attacks" as some may be from large mining pools processing payouts to various miners, not having their payout TX confirming when they find a block then including a set of TXs that would payout to miners but may not include the original inputs that the TX had that were originally propagated to the network. This would appear to be a double spend while everyone would still get their bitcoin so it would not be a true double spend attack

No problem, do not worry.
