Occupancy is a night count divided by rooms that were actually for sale. Houses forget the second half. A room closed for plaster is not a vacant room. If you leave it in the denominator, you will look busier than you were, or emptier, depending on the month, and you will not know which.
What the ratio can say
Set against Imereti houses of similar size, occupancy can tell you whether a quiet January is a local weather or a house problem. It can show whether a festival week moved the needle in Kutaisi the same way it moved Tskaltubo. It can support a conversation with a lender who has only seen a coastal brochure.
What it cannot say
It cannot say whether the rooms are loved. A full house of one-night stays and a full house of week-long guests look the same in the ratio and different in the laundry. It cannot say whether the rate was given away. It cannot judge a house against Batumi in August unless the house is in Batumi and the month is August.
A note on the “country” figure
Trainers and articles sometimes quote a Georgian occupancy number as if it were a neighbour. That number usually mixes coast, mountains, Tbilisi apartments, and wine-route houses. For a Kutaisi inn it is a magazine, not a benchmark. When we draw occupancy, the caption names Imereti, the size band, and the months. If a house wants the national figure in an appendix, we will print it with a warning box, not on the main plate.
Keep the night book in one hand. If two people write in it, mark the change of hand. Mixed books are the usual source of a phantom spike.
