Are they using some software for this or was this built in-house?
The world runs on computers. It is as essential as oil for the functioning of societies. Increase in silicon costs is going to increase costs unilaterally across the board. It happened during the pandemic and something similar will happen now. If anything it should be a wake up call to countries to start thinking about securing their own supply chains.
But I don't think the paper claims that they beat the market. What they are concluding is that you can classify investors as skilled and unskilled, with the skilled group able to achieve returns consistently. But whether those returns can beat the market, they say the evidence is limited.
Did the paper say the same set of people consistently beat the market over long periods of time or did it say at any time about 10% of investors happen to beat the market?
> The Calm Act refers to A/85, and A/85:2013 specifies BS.1770 (specifically referencing BS.1770-1) as the source of its loudness measurement techniques (1770-2 did not exist at the time A/85 was finalized). So BS.1770-1 currently serves as the yardstick by which U.S. television programming will be evaluated for CALM Act compliance.
> BS.1770 recommends the Leq(RLB) measurement algorithm, where Leq(W) the frequency weighted sound level measure, xw is the signal at the output of the weighting filter, xRef is the reference level, and T is the length of the audio sequence.
> The drawback of BS.1770 as originally conceived is that it measures average loudness over the entire length of content. This may be fine if the loudness is fairly consistent over time. If not, a quiet section of content may, as illustrated in Figure 5, bias the average level so that it measures as acceptable despite having some sections that are unacceptably loud.

The long term consequence of this is that as capital gets concentrated into fewer and fewer hands, so does the means of production. If you are outside the network you will find it very hard to sell your services even if you have a better product. This already happens in many places with wealth disparity. Deals simply do not happen without the "blessing" of a wealthy backer. Software is unfortunately moving that way. The once upstart nerd who was able to launch their business from the basement has turned into the technocrat baron who will keep such a thing from happening again.
