As I put more data in the spreadsheets are taking an age to complete is that my computer or is it as is
That is how it is with so many calculations
I have a different sheet for each course and link them to a database
This can be useful because you can spot trends in each course distance.
The sheets I use have even more calculations and just 3 1/2 years of data for Wolverhampton has 17000 rows by itself.
If you didn’t want to have one for each course, you could split into AW and Turf
But there is no avoiding it excel can only do what it can do, that’s why originally I had the sheet set for 20000 lines but I made it do 200000 for you , bit too much for one sheet.
How many months data do you have in the sheet now?
