Mob Spawn rate (enderman) Bedrock

Recently i created the same as Ph1lza ( the famous 5 year hardcore world) series 4 enderman farm in bedrock edition with no mistakes. He get so many endermens in one minuite and i get instantly exactly 10 enderman in a row. doesnt matter if i stand there 30 minuets or more , it will be exactly 10. This is outrageous , the difference with java is so big. Please do something about spawn rates, its also boring and easy in outside of the world too.
