Freestyle stroke advice Please (video included)

I learned freestyle a year ago and recently hit a major personal milestone of sub 1:30 for an all out 100m sprint (SCM). Very happy about this :-D. Here is my stroke video. www.dropbox.com/.../Oct-8-2018-free-all-angles.mp4 Three months ago, my all out times were 1:39.6 (100m) and 0:21 (25m). Now they're 1:29.8(100m) and 0:20.2 (25m). So clearly I'm making more progress aerobically than stroke technique-wise. I'm guessing/assuming 25m all-out speed depends on technique. All-out 100m: 1:29.8 (spl: 24) All-out 25m: 0:20.2 (spl: 20) css-pace: 1:40 (I can do 10x100 with 20 second gap). My spl ranges from 21-22 for these 100s. I do mostly 50s and 100s (trying to pay attention to stroke count). The only drill I currenty do is single-arm free style (8x25 on each side). Since I started this drill a month ago, it has improved my DPS a lot. I swim 6 days a week (12km). My next target is 1:20 for 100m :) I would love to hear your feedback on what I should focus on next.

  • After the feedback from @Swimspire, I really wanted to improve my kick and started doing kicking drills. Thankfully, I found out that I can avoid cramps during kick drills if I have a banana and an electrolyte drink before swimming. My 25m all-out speed with absolutely no kick is only 1 second slower thanthe one with my current "2-beat" kick. I'm really curious to know how this matches with others. So I'm on a mission to find out what a good kick can do to my 25m all-out speed. I am finding kick sets (8 x 25m) to be quite tiring and I need atleast 1 min rest after each 25m. My typical times are around 35s per 25m and my fastest so far was 31s. I read that good swimmers are only 2-3s slower with kick only compared to full-stroke. I'm a full 11+ seconds slower now. I would really like to know what I'm doing wrong and how I can improve. My kick video and the same video at 0.25x speed.
