When RYR check-in, bag drop, whatever they're calling it this week, closes at something like STD -40mins it's pretty obvious that one isn't going to disembark one flight, walk for half a mile, collect any baggage they may have, then make it from airport arrivals to departures only to realise they're at the wrong end of the departures hall etc.
Two hours should be recognised as a minimum, sure if one is booked on one thru booking then 45 minutes might suffice providing that one accepts that their checked-in baggage might not make the connection.
Airports/Airlines such as ZRH & Swiss have PDQ transfers off to a fine art, STN & Ryanair do not ... Well they simply don't do transfers!
