Aggregated reports are invaluable for studying and implementing a GTO (game theory optimal) strategy in poker. They provide a comprehensive overview of a player's postflop strategy, including information on expected value, equity, and range advantage.
Also known as macro reports, they help identify areas where you can improve your strategy, such as spots where you are over or under-bluffing, or finding opportunities to increase your win rate and profitability by adjusting your bet sizing or range construction.
These reports can be viewed in the Range Converter Online Range Viewer, so there is no need of buying a solver for that.
