Operating Profit Margin deciles

I've dug through Sharelock, and obtained operating profit margins for companies having a market cap of at least £200m.

Here are the deciles:
P0   -235.43
P10     3.50
P20     6.22
P30     8.37
P40    10.86
P50    14.22
P60    18.11
P70    21.54
P80    30.43
P90    49.24
P100  109.40


I have excluded companies that do not have OPMs. These are mostly financials.
