The MinConnectTime is airline's own acceptance of risk (if there is a delay, they bare the costs of rebooking you)
As [MENTION=229854]MSPeconomist[/MENTION] mentioned, you don't have a connection/transfer. You have separate tickets, any issues and you have to rebook yourself on a new ticket
So what is your acceptance of risk? Just today, the incoming flight was delayed by 52 min, which means you wouldn't have made it

This is the past historical stats, with caveat that past doesn't mean future performance

Also,looks like it sometimes land in T1S? Could also be bus Gates?
