edit: make sure you check szlamany's post first - he's a bit of a pro at this sort of thing!
So are you just moving those columns (and a copy of the Pol_no column?) to another table? If so, that wont help much - in fact it will probably just slow things down, as all you are doing is adding an extra join (and no benefit).
Do you have any queries that have something like "...WHERE Team = 'Team11' ..."? If that is the case (and there is lots of duplication) then a separate table for those columns would improve things.
The table for Team would contain data like this:
(basically the unique values from the main table, and an Autonumber/Identity field for the ID).
The main table would then store just these ID's instead of the text (so 3 instead of "Team7"), enabling queries to be faster even with the extra join - as they will mainly be comparing numbers instead of text.
The query could then change to something like this: "...WHERE TeamID = (SELECT TeamID FROM Teams WHERE Team = 'Team11') ..."
Doing this does mean tho that you will need to use a few joins in your queries to return the full data (assuming you do the same thing to a few of the columns). I would suspect that it would still be faster tho.
I don't know how much work it would be for you to change the app (or even if you will be allowed the time!), or even if there will be obvious gains from doing this. What I would recommend is 'copying' the main table to start with, and make these changes to the copy - you can then run similar queries on each to see what sort of difference it makes.
