The Double Cyclone Drake II gets 800 on the MaP test.
A normal flush needs 250 grams.
The EPA gives their Watersense sticker if it flushes 350 grams.
Everyone that does testing thinks that anything 500 grams is very good.
You must love numbers, because you will never ever see more then 400 grams being flushed.
The video below is a 1.6 gallon flush Drake, but it's good to show much much 800 grams is.
For example, I was using a Toto Ultimate one-piece toilet for two years in a high use area without plugging it.
It was rated at 325 grams in the MaP testing. I pulled the Toto and installed a Class Five Kohler Cimarron, and that one plugged weekly. I then removed that one and installed over at my daughters home in Lynnwood; she has two Toto Drakes and the one Cimarron. She's been bugging me to get a third Drake.
There is a balancing act between bowl rinse and bowl flush to be sure.
I use some toilets while I'm out, and while I was at the movie theater Sunday, I had to flush five times with a flushometer bowl. I could not see the brand on the bowl, which was strange, and I was in the mens room for a while flushing the darn thing. There was very little bowl rinse from the front of the bowl, so even if it had been map tested, with high ratings; because it's not all about things dropping precisely into the drop zone. If you manage to drop everything into the "drop" zone, you have a better chance of clearing the bowl. Woman tend to drop paper in the front of the bowl, and some brands that get 1000 on the MaP will leave paper on the front of the bowl. Most of the water is diverted to "pass" the MaP. MaP knows this, but they are committed to years of testing that didn't look at that problem. For them to "change" the test, would mean throwing out all of the old data and starting over.
I on the other hand, have always had customers that "demanded" bowl rinse. More then half of my testers are women and children. I don't really care about the engineers that like to flush round golf balls. Golf balls never stick and they always bounce their way down the drain. MaP has gone to plastic wrapped paste in the last few years. When they did that, all the scores went up. When you have slippery plastic, you can flush a lot more bulk.
In my case, I have been using an
ileostomy bag, and it gives many bowls problems. I plan to use this method over the next year until I finish up with two more surgeries. In the mean time, I can tell a lot about bowl wash. The Ultramax II will clear most anything in one flush. Sometimes, if I have been eating chocolate, it may take a full handle down flush to clear the bowl. When I use other brands, it can take five full tank flushes. That's sometimes 15 gallons to clear a bowl. The most I've ever seen the Ultramax II need is 3 gallons. 95% of the time 1.28 gallons is all that is needed.
Lowe's Movie theater in Lynnwood, fives flushes at 15 gallons
Kohler Memoirs, Ingenuium Flush, 15 gallons
Safeco field flushometer, 7 gallons
University Hospital flushometer bowls range between 3 gallons and 15 gallons depending on the bowl. They have American Standard and Kohler.
And let me repeat this
MaP does not test for bowl rinse. They haven't a clue on this.
There are two big complaints that I get:
1) Flushing of solid waste, does it plug? MaP does test for this
2) Cleanliness of the bowl after the flush, Map does "not" test for this, I do however take this into account when I do my reviews. There are many people that view this as important, and so do I.
The MaP test is only one part of the seven things that I look at.
Cased Test Media.
If you wrap the "test" media in a condom, how will you know if the rinse water removes the streaks?
3.1 Soybean paste nominal specifications: 35.5% water, 33.8% soybean, 18.5% rice,
and 12.2% salt, and having a density of 1.15 ± 0.10 g/mL (i.e., density greater
than water).
3.2 Cased Test Media:
3.2.1 Latex casing shall be made from non-lubricated latex condoms (e.g.,
LifeStyles® brand, purchased from Ansell Healthcare Products LLC, Dothan,
AL 36303 USA).
3.2.7 Individual test specimens shall be discarded after they have been subjected to
100 flushes.

I don't know about you, but flushing something 100 times?
Consumer Reports uses rubber sponges, mainly because they can reuse the testing media.
Do any of us need to flush rubber sponges or things wrapped in rubber?
