Mean response time?

Hello,

When looking into results generated by report generator, I assume that there
is certain kind of relationship between mean response time and hit ratio,
which is:

Mean Response Time = Hit Response Time x Hit Ratio + Miss Response Time x
(1 - Hit Ratio)

However this seems not true after real calculation using data in the report.
I am really confused, could somebody help me find out what is wrong with
this equation? Many thanks to your kind help.

Ping
