What is the difference from scoring in the historical table and the score that i see in the playing table in the top left box (IMPs)
Why they are different ?

It's just an issue with timing. Other tables are playing the boards, and your score changes when those results are included. The historical results and the summary table result update at different times, which means there can be discrepancies. In the long run they will be the same.
