No I never test my 1RM. You need quality volume. You have no need to do 1RM stuff unless you are a powerlifter or doing some sort of competition where that matters.
I would focus on your 5RM, 8RM, and 10RM. You will get strong using any set/rep scheme. Don’t confuse testing with building. If you turn that 240x1 into 240x10 I promise you your 1RM went up without ever having to test it. You are trying to raise your floor and get stronger, not reach your ceiling.
I personally say start with one day of lower reps (5x5) and then do one day of high reps (5x10). That approach as worked very well for me. But I am also 5’7. Since you are 6’2 you might find front squats, etc work better.
Since you workout at home, you should look into CT’s Simple Guaranteed Strength and Size program. Trust me your legs WILL get bigger and stronger.
