One test that would be easy to do, or relatively easy to do, would be to set up a simple tank, one slow growing plant - anubias? - ordinary pool filter sand. Add some terrestrial plant food - with urea/ammonia in it. Then set up about 2 watts per gallon of light and run the lights on for an hour a day only. (The room would need to be darkened.) Watch for algae. If algae blooms, then it can't be true that algae require long periods of light to bloom. If no algae after a couple of weeks to a month, increase the time the lights are on to 2 hours a day, etc. The obvious flaw is that not all algae are alike. Green water algae could and probably would start growing, but that wouldn't mean that BBA or GDA or GSA would do so.

I agree that you would likely have to replicate noon-burst or split photoperiod on 100's of tanks, keep all other variables(ferts, type of water DI or Tap, types of plants, fish stock, substrate, etc.,) to confirm beyond the shadow of a reasonable doubt the benefit of these as anti-algae measures. This would involve a significant financial cost not to mention time.

While I know my experiences don't speak for everyone, under two identical 10 gallon tanks, with all other things being relatively equal, I found that noonburst and split photoperiod "appeared" to result in less algae(with the exception of Blue Green Algae). The difference was that the plants seem to respond better growthwise to noonburst lighting vs split photoperiod.

Just my own observations, nothing more and nothing less.
