All candidates in post below need Q >720

You can read the posts in the above thread (towards the end). We were finding benefit of using Q values greater than 50,000

You can also artificially create a sequence that needs Q>720 for testing

It would be best for a manual option for Q as some sequences require Q to be a multiple of 7,11 etc and it is hard for any algorithm to predict best Q in all possible circumstances.
