IMO, Tsurikomi Goshi (not SODE Tsurikomi Goshi) is just a training tool for getting your entry and hip placement for Uchi Mata and Harai Goshi. If you throw Harai Goshi with a HCG and a high elbow then that's how you should throw your Tsurikomi Goshi when practicing it, if you throw Harai with an over the back grip then that's how you should practice your Tsurikomi Goshi.
The only time you see Tsurikomi Goshi in shiai is when uke has gone flying before the reaping leg has entered.
I might need to get my coaches to check my tsurikomi goshi again. It seems like my hips are a little further across than they are on my harai's and uchimatas.
I actually don't think I have ever used tsurikomi goshi in randori but that is just how they explained it to me.
My training has been on the hold a lot the last few months other than a handful of classes. New year I hope to be able to go more and also may be getting a grappling dummy to practice my throws on in my off time. I thinking I may try and work through the gokyo with it. Maybe work on one throw a day and just work may way through and then start over or would it be more beneficial to do it another way?
