Is it possible to determine the vertex count of a fluid simulation frame without applying the fluid simulation?

Normally I would just go into edit mode and select all to see the vertex count in the Info panel, but its a nuisance to have to duplicate and apply my fluid mesh every time I want to see this information. (e.g. if I'm going through the frames and watching the vertex count)

Is there an easier way to do this?

When in object mode the info panel shows the vertex count of every object in the current scene which includes hidden objects, with a fluid simulation this changes each frame as the fluid mesh changes.

The frame before the fluid simulation starts will show the scene vertex count to use as a basis, lets start at frame -1 and say we have 16 vertices for a simple simulation with a cube for fluid and another for domain. Jump to frame 20 and we have 17184 vertices. By subtracting the 16 vertices we started with we have a fluid mesh with 17168 vertices. For an exact figure I believe the 8 vertices for the domain are included in the deformed fluid mesh so should not be subtracted from the vertex count of the frame.
