Credit Card Demo reports incorrect number of inference steps

[rosielickorish]

Describe the bug
When running the credit card example there is an output line showing something like this:

** *** Performing inference on batch 23/184 *** **

But the demo by default actually does 24 iterations. The output line should be updated to reflect the number of interations performed.

To Reproduce
Steps to reproduce the behavior:

1. Run the credit card fraud example
2. See the output from the demo

Expected behavior
The output from the credit card fraud example should say

** *** Performing inference on batch 23/24 *** **
