help with sudden signal fall

[RENN]

i have a scaled input from the daq device which varies from 0-200.

i need to detect sudden signal falls.

but the signal is fluxuating and is read every 100ms. but its fluxuating values limit me from using Peak detector vis. 

i made a vi which detects sudden fall of values. it monitors last 5 points and if the difference negative, it's considered as a signal fall.

please have a look at the vi attached.

the floating point digit is rally fluxuating. will it be better if i use integer instead?

Please post some real data.  Run your program until you have at least one and preferably several "falls" in the data.  Then make the current value of Array default, save , and post the VI with the default data.  Without some data to examine, we cannot comment on the effectiveness of your VI.
