I am not certain about the bloom in Finland but there are place here where 60 hives to a yard is pretty much standard operating procedure. .
That research was from Australia.
But if it standard, you keep your hives in 50 hives punch.
We have a standard 10 hives in one place. That same figure was 80 years ago and still valid figure.
Problem is that pastures have changed totally and hives are 4 times bigger than 80 years ago.
It is same with rape. 50 years ago standard was 4 hives per hectar and it is still the same and hives are 3 times bigge now.
Australian have critical attitude against those "standards". I just told my opinion and you keep those 50 hives in one punch and get 100 kg per hive. I wonder how you get 5000 kg honey from one point.
But your average yields are far from 100 kg or even 100 pounds
http://outdoorplace.org/beekeeping/honey1.htmHoney production in 2004 from producers with five or more colonies
totaled 184 million pounds, up 1 percent from 2003. There were 2.56
million colonies producing honey in 2004, down 2 percent from 2003.
Yield per colony averaged 71.8 pounds, up 3 percent from the 69.9 pounds
in 2003. But do beekeepers tell the truth about their yields. Not at least in my country. The truth for tax collectors is something. No one can earn his living with such figures.
How many hives ... I have not calculated.
In eastern Europe hives have vanished but they have not been calculated ever.
