i had a pigeon that won 4 races from 107mls well up in the fed each time every time i sent him to 300mls which i did twice he would night out, one paticular year i never sent him to the 300 ml race as i thought i would be waisting my time, approching the end of the season i put my widowhood cocks to together with their hens ready for the 500ml combine race, this cock was doing things that i had never seen him do before so i sent him, he ended up 27th open with over 5,000 birds competeing with only 102 birds home on the day. so the awnser to your question is imo is yes.
