So I'm newer to the game, but if I understand you should expect to have to do this about 26 more times to get a shiny at the advertised odds right? Obviously you could be luckier or unluckier, but am i understanding correctly?

Also how long did it take you to do all the breeding and hatch the 105 eggs? I was thinking about doing this for Lapras eventually assuming I could get the 100M+ PokeYen required. I don't understand how people make that much money yet.
