If it keeps working go with it! I'm not very fastidious about my pollen chucking, I figure that they are all quality genetics. I collect my pollen indoors in the spring, but I could easily get some cross contamination when I am collecting pollen from 2 different males that are in 2 different tents in the same room. If I tried to run males outdoors the Oklahoma wind would get more pollen than me.
I grow my males outdoors and wait until the first male flowers start to drop downwards like they do before opening, then I cut the top off bring it inside so it's isolated from the outside plants. Then I put it in a vase in a window and collect the pollen as the flowers open.
Moisture makes pollen nonviable, so after I dust a branch with pollen I cover the pollinated branch(with a bag or something), then mist the rest of the plant(s) that I don't want to be pollinated, with water. That way you don't get cross contamination of pollen, or seeds other places on the plant where you don't want them.
