I recently outputted multi project trap data for the period 10 May 22 to 10 May 23 for seventeen projects.
Threw that into excel and created a pivot table to summarise data.
To quickly calculate corrected catch rate, I did this for each project in Trap.NZ (one by one).
The total number of catches (disregarding none) differs between the trap summary and the calculated catch strikes in six projects (~0.3% to ~15% over or under).
The numbers are quite similar so it is not a big issue, but there is a difference.
I must be overlooking something simple - any help?
