FLR(M) Supporting Evidence - multiple change of addresses?

[rarbg]

Asking this on behalf of my friend who's about to lodge his second FLR(M) for his wife.

They've lived at 5 addresses in 5 different cities over the past 2.5 years (sounds crazy but it's due to work) and only just last week moved into their 5th and hopefully final property.

They have ample supporting evidence, over 30 items - both in joint names and addressed in sole names. But they are nearly all spread over the previous 4 addresses and they only have 1 item from the new address they moved into last week.

Is this fine? It will also be explained in their cover letter.
