Amit its important to note that dismax/edismax isn't giving you a weighted average of these field score. Without the tie parameter one fields score is likely always "winning" the dismax contest. Field scores are relative, so 5 could be an amazing score for say "title" while 500 a terrible score for "text". Dismax picks the field that yields the maximum score, so the worst text scores might be sorted higher than the best title match.
Look at your debug output and use that, rather than your sense of relative field importance, to adjust qf.
