nope, it's not default 28, it's various for different IDs.
When you nmiss your target ID input the one you've got to the seed finder window. And now, for example you had to advance frame 5 times. Reporter says you hit frame 45, so your starting is 45 - advances (5) = 40. Now, if reporter indicates, that your ID is on frame for example 35 - CHANGE THE SEED - there's no way to hit that...
If reporter indicates that your frame is 43, then you have to advance frame only twice.
There's no default starting frame unfortunately, so if your starting frame is higher than the one you want to hit, you have to change the seed :C
I fortunately got my 00001 ID in Black with ease! Second try was successful :)
that was my 1st non c-gear seed hit by the way.
