Finally got an instant approval!
P2 applied for a CIP today on the 100k offer and was instantly approved with a $5k limit.
Sole prop using SSN, $0 business revenue but high household income. 2/24, last Chase approval was a personal card 3 months ago. Did NOT proactively lower the other business card credit lines this time. Will try to instead transfer some credit limit from other Ink cards to this new one in order to make some big purchases.
