I don't know the metrics but I think they vary by ride and by park attendance (or expected attendance). In the past, I have tried to get Tron maybe 7 or 8 times and I hit it once in the morning. I have tried Guardians maybe 15 times and I have gotten a total of 2 morning lottery hits and 1 afternoon hit. Of all the virtual que's I have ever tried,...I dunno, 90% were failures only 3 seconds of availability.
Granted, I stopped going to WDW as of Feb of 2024. So I can't speak for almost all of 2024. Maybe Virtual Que was MUCH better in 2024 then before that time. My entire 2024 WDW budget went to Tokyo Disneyland & Disney Seas this year. (I flew there specifically to ride "Splash Mountain" again) My entire 2025 WDW annual pass and hotel/food budget has now moved to Universal for the first time ever.
So,..no WDW for me in 2025. (No reservations, no lightning lane, no virtual ques, no more headache) and I think I'm back to Tokyo in 2026 because I had so much fun in "their" Disney! (I think it's cheaper too! Single day park ticket is $65 dollars and those parks are stunning)
