to the previous poster, megara is a script copy/paste reader unfortunately. i was sad to see that since i loved her the first time. if you want to test if your readers are copy/pasting, go back to them from another device (e.g. a friend's phone, a computer at the library) and go per min so you can exit out when you see how clearly it is a script. unfortunately bitwine forces us to spend $10 to review, otherwise we would have been able to "catch" a lot more copypaste readers by now.
to the original question, i think that these things take time. within a month accuracy seems decent to me if this is a person you are estranged from. context is everything. also, the shorter term the prediction, the more accurate it is likely to be
