The fourth round of the SLP 2010 year brought balanced and interesting results, while the ranking on the front bars once again confirmed the quality and perseverance of the experienced listeners. The most points in this stage were won by Jozef OM3-0001, who claimed his first victory this year with a total of 9656 points. After several months of stable performances, he managed to take advantage of regular participation and accurate processing of reports, which moved him to third place in the running order of the entire competition.
Jan NL6828 finished in second place with a result of 6280 points, thereby consolidating his position among the most active participants in the series. Jan has been in the first half of the table for a long time and his results prove that patience and consistency in listening and recording connections bring stable results.
Third place in the May stage belongs to Bill W1-7897, who scored 6206 points. Bill, the winner of the second stage and the second man in the overall running order, with this performance kept in close contact with the leader Vladimir R3A-847, who, however, did not participate in the competition this time. Thanks to this, the gap between the two listeners narrowed, which promises an interesting continuation in the next rounds.

Fourth place went to Hans NL7403 with 5390 points, followed by Johan NL9723 with 4680 points. Both are stable participants in the series and confirm that even with a smaller number of received stations it is possible to achieve quality results. The first seven are rounded off by Rachèl NL13498 with 2160 points and Ad NL9745 with 2144 points, separated by only a small difference.
In the running order of SLP Competition 2010, Vladimir R3A-847 remains in the lead with a significant lead and a total of 108,669 points, followed by Bill W1-7897 with 83,373 points and Jozef OM3-0001, who has 52,699 points.
