Hullo, just like to inquire. Before doing the testing, did you service the original bearings? Clean them totally clean, removing the original lube? Then doing the test with with the original and boca bearings with the same lube?
I’ve done some tests like this and found there is no difference in distance once you do this. The best way to get the best performance out of the bearings is to clean them up and use low viscosity bearing oil. It’s not so much the bearing “quality”. The new bearings from boca are delivered dry, so they will perform better than the original bearing which are normally lubed with heavy oil.
Economist Steven Levitt and Gladwell have a running dispute about whether the fall in New York City's crime rate can be attributed to the actions of the police department and " Fixing Broken Windows " (as claimed in The Tipping Point ). In Freakonomics , Levitt attributes the decrease in crime to two primary factors: 1) a drastic increase in the number of police officers trained and deployed on the streets and hiring Raymond W. Kelly as police commissioner (thanks to the efforts of former mayor David Dinkins ) and 2) a decrease in the number of unwanted children made possible by Roe v. Wade , causing crime to drop nationally in all major cities—"[e]ven in Los Angeles , a city notorious for bad policing".  However psychologist Steven Pinker has suggested the second factor relies on tenuous links.  
The International Maritime Organization (IMO) has helped to make the seas cleaner and shipping—which serves about 90 per cent of global trade—safer and more secure. IMO measures cover all aspects of international shipping—including ship design, construction, equipment, manning, operation and disposal. With the help of IMO, ship losses have fallen and fatalities decreased; pollution incidents—including total oil pollution—are down; and air pollution and pollution from sewage are being addressed. These improvements are taking place even as the amount of cargo carried by sea continues to increase: the total of goods transported by ship reached billion tons in 2013.
