But there are still kinks to work out. Unfortunately, both the comet tail and the distance counter were a bit inconsistent as the homers continued. Casamona believes there were two key factors that contributed to the complications: a significant amount of radio frequency noise was apparent at the stadium, muddling the radar signal, and the radar's conical beam's inability to track high-flying pop-ups, which explained why certain hits, which reached up to 135 feet, were lost in mid-air. The solution could be multiple radar systems pointing in different directions or radar with a wider beam.
Compared with the present, professional baseball in the early 20th century was lower-scoring, and pitchers, including stars Walter Johnson and Christy Mathewson , were more dominant. The " inside game ", which demanded that players "scratch for runs", was played much more aggressively than it is today: the brilliant and often violent Ty Cobb epitomized this style.  The so-called dead-ball era ended in the early 1920s with several changes in rule and circumstance that were advantageous to hitters. Strict new regulations governing the ball's size, shape and composition, along with a new rule officially banning the spitball and other pitches that depended on the ball being treated or roughed-up with foreign substances, followed the death of Ray Chapman after a pitch struck him in the head in August 1920. Coupled with superior materials available after World War I, this resulted in a ball that traveled farther when hit. The construction of additional seating to accommodate the rising popularity of the game often had the effect of reducing the distance to the outfield fences, making home runs more common.  The rise of the legendary player Babe Ruth , the first great power hitter of the new era, helped permanently alter the nature of the game. The club with which Ruth set most of his slugging records, the New York Yankees , built a reputation as the majors' premier team.  In the late 1920s and early 1930s, St. Louis Cardinals general manager Branch Rickey invested in several minor league clubs and developed the first modern " farm system ".  A new Negro National League was organized in 1933; four years later, it was joined by the Negro American League . The first elections to the National Baseball Hall of Fame took place in 1936. In 1939 Little League Baseball was founded in Pennsylvania. By the late 1940s, it was the organizing body for children's baseball leagues across the United States. 
Most players believe they are swinging down as that is what they were taught and learned early on. Players that make it to the next level adapted either purposefully or unconsciously. It is really a function of necessity to be able to compete with the top level pitchers they are facing. When they find they are outclassed and struggling, either by instruction, intuition, emulation, or experimentation, they adapt to keep up. The successful ones make it to the next level and vice versus. As a successful player’s swing develops and is refined over the years of countless repetitions, he often lacks a conscious awareness of what he is actually doing, but rather his subconscious develops his motor skills based on successes and failures. What is fascinating is that we see overwhelming evidence that one swing path is the only swing path that is predominantly successful. And what is equally fascinating is how few people recognize this, including the very players that are swinging successfully with this technique.
