2 years ago, Ed Marter released a video demonstrating a knowledge of full 1 Look Last Layer, he is believed to be the first to genuinely know all of the algorithms to solve the last layer in one look without influencing it beforehand.
Most speedcubers solve the last layer in two looks, usually OLL where the layer is orientated and then PLL where the cube is finished off, the total number of algorithms for this is 78. Solving the last layer in one look is theoretically going to be faster, however, the number of algorithms is very high and depends somewhat on how it is counted.
A simple criticism of Ed Marter is that he may know full 1LLL but he isn't able to utilise it very well as there are thousands of cubers who are faster than him without knowing it but it is still very impressive that he has been able to learn and recognise the thousands of cases required. This week, he demonstrated that he still knows all of the cases and algorithms he learned two years ago and now seems to be slightly faster both at recognising the cases and at F2L beforehand.
He also seems to have finally bought himself a better cube but has changed the colour scheme for some reason, he seems to have swapped round blue and yellow, I have no idea why anyone would do that, it seems very strange, he also now always solves a blue cross so that the centre on his last layer is white.
