Is there a better way to test if a indicator repaints?

What is the quickest way to test if an indicator repaints?
I've been using "on demand" and staring at a 1 min chart on 3x speed.
Is there a better way?

Top Four Repainting Scripts:

1. Regression indicators (scripts containing Inertia functions).
2. Recursive statements (recursion overwrite themselves) using Highest and Lowest. Essentially erasing and repainting new high and lows. (REVERSALS, HoHo, Swings, Pivots, ZigZags, etc.)
3. MTF indicators. Which attempt to predict CLOSE, dozens of bars before the higher timeframe actually closes (any script containing "aggregation period")
4. Forward-looking equations. Which attempt to predict the next bar and then erases it when reality hits. (this is the only difficult script to easily identify. There will be a [-1] coding involved but obviously if you are not a scripter, it will not be easy to recognize).

Forward-looking scripts are few and far between. 95% of repainting indicators are easily recognized in the top three categories.
Most of the time, you don't even have to bother to look at the actual code:

1. Regression and Recursive Repainters are PERFECT when looked at historically on a chart. They show the perfect low and the perfect high, perfect trend channels. Perfect doesn't happen in the real world.
2. MTF indicators have a classical step pattern. Straight lines until the higher timeframe closes which results in a spike when reality hits and then more straight lining.
