I did my best at Sidus, interesting is that indi components match but signals vary, I think it's something to do with data alignment as counters are used. Other thing is FSB goes from left to right (at least I coded it to do so), MT goes from right to left, again it can have an impact on the counters and therefore signals. I conclude that the indi works the same way as the author planned, but differences in calculation starting and ending points may bring up signal indifferences.
