It would seem that most of those are from opening new accounts and meeting minimum spending on multiple cards which is probably a reason your Ink+ is in pending. That's an "aggressive" churn of accounts to get points that most people won't do or won't meet the spending on to make it worth it.

Most people take a year or two+ from starting research to booking a J or F trip. For me I am entering buying a condo so don't want so many hits at once on my credit but want to get points so my churn was 2 cards instead of 4-5. It's working well for me but your plan may be working well for you but everyone's plan will be different.
