When using the math blocks in nTop Platform, it's always a good idea to write out the equations first so that you can re-create it after using blocks. Workflows like these can easily be converted into Custom Blocks, where you can import and re-use the workflow. Download the example file and try making your own custom block, then compare it to the custom block available for download. One of the great things with nTop is being able to package all of your hard work to be easily re-used again!
