Formulas for derived events can be put directly into the ASCII output of
cachegrind/callgrind, see section 1.7 in
http://kcachegrind.sourceforge.net/html/CallgrindFormat.html
but also see below...

Unfortunately, this is only for pure cachegrind output. You can merge them
at visualization time in KCachegrind via File/Add.. I have a merging tool
on my TODO list.

Open the context menu with the right mouse button over the row of the
CycleEstimation
event, and choose "Edit Formula". Or double click on the formula cell for
editing.
