I agree got alot to do with there systems, but i bet these people in the past all have paid out what there pocket can afford the best birds avaliable to them, having good pigeons has also alot to do with winning. But the percentage of the system and fancier has increased especially in the sprint and middle distance racing, i think the system has a higher percentage towards the system and fancier and less pecentage towards the pigeon in the sprint middle distance maybe 65% system and fancier to 35% Pigeon. However in long distance think thats a different can of worms, has alot more to do with the pigeon then the fancier and his systems, id say along the lins of 75% pigeon to 25% system and fancier. These long and extreme distances need good pigeons, they can be held over at the race point for example lerwick for upto and systems over then a week, the fancier has had no interaction with the bird, but that bird has had that love of home after being held over for such long periods, then to travel 600 miles, pigeons with big hearts and strong minds win these races and further
