Oh and I meant to say, not sure where you get 5 hours from? A few minutes with a modern HUMS (computers are fast these days!). In Bristow we had a policy of requiring a clean post flight HUMS report before a subsequent departure from base. Even if it was a rotors running turn-round in Aberdeen (which takes about 40 mins). When I retired in 2013 I don’t think all other operators did this and it was not required by the legislation or oil company rules. Which was a bit silly!
