Unfortunately, the increased chance is only for people who paid the $15 for the ticket :/ I had nearly the exact same luck last year during go fest, except I ended up with 1 shiny each day playing for 9 hours each. This year I got 27 on each day, roughly 3/hr of playtime Even if you bought the ticket, you’d still need to be encountering ~120 Pokémon/hr to average 1 shiny per hour
