what's the point of total seal rings ?

If you're asking about gapless,I understand the theory, but cannot cite real world results.
The idea with rings is the less pressure loss past the rings, the more pressure is available to push the crank around. Less pressure-loss should translate to more horsepower to the track.
All ICE(Internal Combustion Engine) horsepower is created by the pressure of the hot expanding gasses. It is written that of all this created heat; 1/3 gets into the cooling system, and 1/3 goes out the hot exhaust, leaving just 1/3 for doing the work.
So imagine an engine in which this 1/3 heat of expanding gasses equals 420hp with a typical ring seal of say 2 to 4 %. Then imagine this same engine in which the ring seal is closer to zero. How much more power would that translate to? IDK, but I imagine it would be more.
Now consider that every single moment that the engine is running, the rings are wearing, and the gaps are growing.........But the gapless design with overlapping ends are continuously compensating. Yeah sooner or later they wear out too.
I like the theory behind these,cuz I suppose a guy could run them in a dual purpose machine with hypers, running a bit extra gaps, and not have to worry about pressure loss on the street, nor tearing off the top ring lands on race-day,from too-tight gaps.
On a different note;
In the end I went with with Plasma-moly file-fits. I had excellent results,with nearly immeasurable pressure loss on the LD tester at 100 psi on the day of install; and still was nearly so, 4 years later, with over 30,000 miles. I haven't checked them now for over 10 years, and the engine currently has over 100,000 miles.It still doesn't use oil.Somewhere between 50,000 and 80,000miles (I'm guessing a bit), it went 93 in the 1/8th. At my race-weight 3650,I think that translates to 420hp.I was ecstatic.
