start a 4 day split

[cooldude20142]

I started bodybuilding around 15 Oct 2014. I have gained already around 4 to 5 kg pure muscle . I can already lift 100kg dead lift for 10 reps, 80 kg squat for 10 reps and 50 kg bench press for 10 reps. By this speed I will be gaining around 5 lbs more muscle and lifting around 80 kg on bench press for 10 reps , 120 kg for 10 reps on deadlift and 100 kg on squat for 10 reps after two months. At that time can I switch to the 4 day split based on my strength level. My current three day split although is good but I want muscle definition as well. Is the M&S 4 day split good or Is there any other 4 day split for hypertrophy which I can use two months later ? When will be the ideal time in my case to switch to the 4 day split

My current 3 day split. Also I do 2 abs exercises on two days a week
