No
First raw number of reps aren't as important as the quality of them.
Second, how many days do you think you and the partner could do that many before you both got noted, had other things to do, etc?
Next, if the other person isn't challenging you in new and more difficult and more technical ways you'll stop learning.
Finally unless you have a qualified instructor teaching you how will you correct little mistakes?
Everyone should practice at home but it has to be the kind of practice that reinforces what you learn in class. It can't just be you and your buddies interpretation on what you think you've learned from the Internet or just messing around.
Two points for you:
1) @Tom was correct. The number of times you do something is not important. The accuracy and correctness is. We all hear repetition is the way to improve. However, incorrect moves mean you do not improve. Do something wrong for 20 years, you get very good at doing it wrong.
2) Tai Sabaki does not mean side stepping. It means Body Shifting. Sometimes that would be side stepping. Other times it means other things.
...
No. It doesn't matter how many times you do something. Hopefully you will get better. Mastery IMO is an unachievable goal. One should not seek to master, but should seek to improve.
Tai sabaki is more than side stepping. It is moving your body. It is getting out of the way. It does not have to be side stepping.
Tai sabaki: BODY movement. Tai sabaki is also used to refer to a circular body movement versus Shintai, a straight line body movement.
Ashi sabaki: FOOT movement. Refers to any movement of the feet. Changing stances, turning etc.
Sabaki no ashi: To reposition one's self through foot movements. Inmost classical arts there are eight directions of movement, the four primary directions and the four secondary directions. Along with the direction of movement is the specific foot movement also of which there are close to 20 I can think of right off the bat.
Happo no unsoku: eight directions of angling. An exercise in which one practices moving the feet and subsequently one's body posture in eight different directions, to place one's self into an advantageous defensive position. This is important as being in the right place in relation of your opponent will greatly facilitate your counter and make your technique literally effortless.
Kaihi: To move out of the path of the attack while deflecting the blow. Also referred to as inasu. A paramount movement in all styles of bugei. A name for the movement of one's body.
Inasu:To shift one's body to avoid the oncoming force. A classical foundation of the ju principle in Japanese arts.
Ashi fumi kae: Changing legs. To switch a specific foot forward stance or posture so that the opposite foot is forward. In Okinawan martial arts it is also referred to as hisa keirei.
Noru: To ride the opponent's momentum and to strike the opponent before their momentum stops. A common principle in many classical Okinawan and Japanese arts.
...and I could go on.
As you can see the traditional martial arts didn't just step to the side. They had many nuances of moving the body exactly to the side all of which affected the opponent and one's own techniques differently. This is wherein the difficulty lies, not in the just stepping to the side the way you think. When you can wrap your brain around the differences and understand them and practice them correctly (note CORRECTLY!) your repetitions may be worth something but not like that. Yours is just mindless repetitions without understanding and without any thought or goal as to where you should be after you side stepped especially if you think this is all the same.
If trained properly with correct management of difficulty, then I’d say 1000 per day will do wonders. Then again I think a properly managed 1000 reps per day for anything will do wonders.
Would practicing the side stepping technique with a live sparring partner 1000 times a day make me master it.
