Yes, difficult balance but I did plan mine in advance, moved about 20 years of stuff from the garage (good chance for a clear out), made the route to b ack of house really easy, showed him the existing holes, didn't comment when he suggested throwing cable over the roof instead which would not have worked and thankfully he abandoned, left him alone quite a lot to work but went out about 3 times to see if things were doing okay and at end went into each room with him to check speed. The only thing I didn't realise was that speed with doors open is completely different in this house than speed with them closed (doors are very very solid and everyone has doors closed, perhaps even more than most families) and that zoom/teams for the few days a week certain adult children work from home (one did an interview from my house today even, entirely on Teams) is crucial which is why I have bolstered things with ethernet cables etc.
