A question about performance, using the Saxon Profile tool

Hi Folks,

This is a question about performance. In particular, about the Saxon Profile tool.

I have a function matrix:create. The profile tool says this about its performance:

Average time (net/ms): 0.007

The matrix:create doesn't call any other function. So, the average time required for matrix:create to do its thing is 0.007 milliseconds. Right?

Next, I have a function f:neuralNetwork that calls matrix:create. Suppose f:neuralNetwork calls matrix:create three times. And that's all f:neuralNetwork does. Then the time to execute f:neuralNetwork should be about: 3 x 0.007ms = 0.021ms, right? Well, perhaps a tiny bit more, to account for the overhead of making the function calls, so let's say the total time is 0.023ms. Does that sound about right?
