I Y T is very important as you can have the whole thing fail if you have the anchors or recovery points wrong. I stands for ideal it is a straight line anchor or recovery point say for example in line with your 4x4 cassis as it’s your strongest point. Y stands for YES it works well not as good as I but as the Y is you have two anchor or recovery points no greater than 90 degrees on each. T stands for terrible it exceeds the 180 degree line and will double your load should never be used. Any thoughts on this?
