In this sport, mistakes are also made by parents early on in their child's journey. My advice to you is to do everything you can to avoid falling into the trap of becoming heavily invested in your child's journey / skills / comparison to others (either at her club or at other clubs) / pace of coaching at lower levels / competition level / etc.
Those of us who have had kids in this sport for many years / multiple levels could tell you all sorts of stories about kids who were "rock stars" in lower levels, but couldn't progress when skills got scary. Kids who were mediocre in compulsory levels who took off in optional levels. Weak kids who became powerhouses when they hit puberty. Strong kids who fell behind when they hit puberty. Kids who lose a season due to injury. Kids who lose multiple seasons due to injury. Kids who repeated levels during a plateau, only to take off and outpace their peers years later. The refrain I like to use is, "We have no idea what things will look like a year from now."
My kids' coach told his athletes that, "Those who do the best in this sport are the ones who stick with it." That doesn't mean they all make it to level 10, or qualify for regionals / nationals. It doesn't mean they all make it to elite. It means they make it as far as their personal journey will take them, and they retire from the sport satisfied that they learned all they could from it: about their physical abilities, but also their mental fortitude and work ethic.
You seem very concerned about your daughter's future prospects, and we all get it. But we've also seen parents who take things so seriously that they take the fun out of the sport for their child, and create adversarial relationships with coaches / staff at their clubs. Trust me when I say that you want to avoid this at all costs. And sometimes, that means taking a step back and really assessing how your actions might come across, even if you are correct in your assessment of the situation. Again, most of us who have had kids in this sport for years could share stories of too-involved parents pushing their kids, demanding more from them than they can give, and/or alienating staff at the club. When your child is going to 20+ h/week of practice, *they* have to want it. It cannot be something you want for them.
You appear to have decided that you will try to move your daughter to another club to give her a better opportunity. No one will fault you for that, and in fact many people have told you that they think this is a good idea. But accusing her existing club of just taking the money of hapless parents with non-athletically gifted kids, or of having poor coaching and not caring about it, is bound to raise eyebrows. If a gym club wanted to make the most money possible, they wouldn't offer competitive teams of any kind. Most clubs who offer competitive teams do so because the people who work there truly love the sport. Not all clubs can be "the best", but that doesn't mean that your club isn't trying their best. Also, remember that the gymnastics world is a small one, and even your actions on a message board such as this one could close doors for you / your daughter in the future.
