Mist coat paint/water ratio

Hi, what’s a good mist coat paint ratio? I’ve heard of 50/50, 90/10 and 80/20. Any all advice is appreciated

"The best mist coat ratio varies from the substrate to substrate and product to product. A 4:1 paint to water ratio generally works well for new plaster. A ratio of 1:1 may suffice for old plaster. The same applies to existing and new render. However, you should always follow the instructions on the paint tin – manufacturers may recommend other dilutions."
