Strike rates? How many places.

[Punter76]

Got a query on strike rates.
Say over 250 bets or more, can anyone run figures on their place strike rate too. I want to know if I've just been lucky on the nose. Field size all.

Win Strike rate - 40% ... What is your place strike rate?
WSR 35%..
30%
25%
20%
etc
etc

Thanks,
P76.
