Decided to test my luck with a few of my Synchrony accounts and my Disco and managed to get these increases today:
Paypal Credit: $1550 ---> $3550
Paypal Extras: $4000 --> $5000
Old Navy: $2900 --> $3900
Discover: $5350 --> $6100
It's been a while since I've had a spree like that, but I did get denied for a CLI from Amazon
You nailed it!
