Keep in mind, the TPE is a good way for noob players to get used to the transfer market and what kind of prices are reasonable, buying and selling. I haven't looked at the TPE since I learned how the market worked and you shouldn't either. Take it as it is, an estimate.
Also, like you just admitted statistically, your player is an outlier from the other data that they've compiled on players around your range. You have a unique build where most players do not fall under. So the estimate would not apply to you. Using your knowledge of the market and knowing your player is better than the TP estimate, you can make an intelligent decision on his pricing.
