3) convergent zone; here's some freedom of choice: with more relns, the matrix gets better and better, but it is well established that you generally do not save any overall time anymore => Build the matrix and do -nc2, -nc3
4) far too many relations => trim free relations from the end of .dat file (these are short lines), then trim some more, goto zone 3). But not too much or you will end up in zones 1-2)
does this help?
