I filtered a few deals from my data, where the contract was doubled (or redoubled) and made according to SD analysis.
Not all are correct as DD can give another result, but there is a pattern about making doubles of freely bid slams, just based on points or AK's. Another pater is passing partners T/O D without sure tricks
I assume 30 of these 41 deals should be fixed

I do not expect all to be fixed, and if all the contracts you double go down you are double to few.
But please do not double a grandslam unless it is going down (On lead in NT with an ace, or a sure trump trick, and they can't run)
The stats is that in the 1 Mill deals I use for training, there are about 2%, where the contract is doubled and making. So I have 20.000 boards, if you need any samples.
