When we first released G4X the math blocks were more simple and ran at 1000Hz.  Their rate was reduced to 250Hz later when more complex functions were added and the character limit was increased.  
There were some oversights when that change was made - for example the documentation stated cnt increases by 1 every 1ms, but it was actually only updating by 1 every 4ms.  So that has been updated - it still only updates every 4ms, but its count increases by 4 each update.  

There is only 1 dsp and amplifier gains etc are applied equally to both inputs so it is unlikely going to work well with sensors that need different gains.  

Thanks Vaughan. I understand the a parameter to count on the falling edge (active to inactive)? So your cunning formula counts when changing from inactive to active. Correct me if I am mistaken. Either way you have answered my question nicely.
