It may well depend on the combination of pan, scraper etc. I do believe there is some power in windage work.
Years ago when I was young and had more time than money,(I'm still short on both) I built an oil pan for a 355 sbc. I used a stock pan, bolted it onto a short block and cut the whole bottom out of the pan. I then bent the passengers side above the rail in and created a scraper out of it. I took another stock pan and some other sheet metal to make a large kickout stepped around the starter, and made a windage tray that was circular around the crank and cut slots in the tray and bent the edges up to catch oil spinning around the tray. the circular tray went in under the scraper on the passengers side. The pan was approx. an inch deeper than stock, It showed a quart and a half low on a stock dipstick with five quarts. I lowered the pickup tube the right amount. I ran that engine with that pan on it for years. The test came when I sold that engine in a diff. car turn key. When I made the pan I got in a hurry to finish welding and got the pan warped at the front of the pan rail requiring a good amount of silicone to seal it to the engine. And it wasn't very pretty!! It developed a leak a year later and the new owner took my (MASTERPIECE) off and put a stock pan on it. The car never E.T.ed quite as good. I don't have specifics on air densities to compare back to back, However it never repeated the best E.T. It ran before the pan switch. And he consistently ran about a tenth slower.
This was on a 7000 rpm. max engine. The crank had not been knife edged and may make windage reductions more significant.???
Windage to me is still interesting and a gray area.
Sorry about the rambling on and on but I thought you may be interested in this.
Wasn't rambling on to me, that's the kind of innovation that makes this site so unique. It certainly sounds to me that your effort was worth some power. Thanks for taking the time to post.
