Yeah that is the strange thing.... although it is the (exact?) same rule, one time it is predicted to be fast, one time slow. Doesn't make sense to me. Maybe an internal technical thing?
Is the one with wildcard really faster? I mean it could just be a bug with the snail shown or not shown. Don't know how to test it.
But actually now that I know the rule is
always add a (unnecessary) wildcard at the end, it doesn't really matter anymore. I will use wildcards at the end in cases like this.
