the status before last refresh should be provided. for eg.this pnr, all have predicted confirm. now the status may be rac1/2, we don't know. when you refresh, it comes to confirm. and what we see is wl 18 has ended up in rac. so its a bit of ambiguity. some admins reply that status before charting was rac8 or rac6 or something, but its not possible to provide the status before refreshing all the time. so status before last refresh should be shown to all.
