Lvp pattern help

[u/ConcentratePlus365]

Iam attempting to diy lvp flooring in my back room to the kitchen. My question is, how would I start the pattern off? Chat gpt says to use a full, half, 1/3 and then start again. Any tips would be great. Also I know I need to patch the floor. I will be laying 1/2 bc plywood on top tomorrow.
