There is a tradeoff between hashrate aggregation and monitoring of individual miners on target pool’s dashboard. This is relevant only for the case that there is used attribute identity_pass_through = true in the TOML config file (within [target] definition). Higher level of aggregation means that individual miners are sending submits slower due to high upstream difficulty (proxy with the high aggregation factor gets a job with a high difficulty from the target pool). In such cases individual miners can appear on the pool's dashboard as inactive. It is not a limitation of the Braiins Farm Proxy but its logical feature.
