So in addition to rank per year manutoo is there anyway you can do rank per year and rank per every 6 months of the year.
For example Serena Williams lets say her rank at the end of 2011 is 8
but Serena in 2011 was injured the first half of the season until Wimbledon.
So maybe like you can do rank per every 6 months(after french open)
The First half Serena was ranked around 180
2011 First Half - 180
2011 Second Half - 8
The second half she ends at 8
Do you see what I'm trying to say? The explanation is kind of messy..
