If the average hunter has a 15% success rate and this bumps it up to 15.001% and another technology bumps it to 15.002% it will go unnoticed, but eventually those bumps will compound and game managers will have to do something because a 1000 hunters are killing 160 elk instead of 150 each year. It might mean less days in the field per person, less total hunters in the field, etc.
I was saying there's no way to collect the "unrecovered" percentage_ ... those animals that are killed but not tagged, because they were not recovered. Its almost a taboo topic, but I'd bet the number of elk that die in Colorado during bow season is double the number harvested. So, even if one piece of equipment increases the success rate by 10%, it may be reducing the "unrecovered" percentage by a similar amount - offsetting any reduction in tags that might occur.
