Well done my brother, next time count the main pressure and divide that by two , otherwise hot side overpower the cold side or other way around or if you wanted dead on , keep adjusting it and keep using the water gauge meter 😂 from the highest floor of the house , wherever there’s a bath mainly , because some showers are designed to mix manually, and with differential pressure it’s absolute nightmare to balance them out 😅😂🙈 same applies to a mixer showers 😅 sometimes temperature will be lower even mixer bar says 42 Celsius on standard shower .
