You are right about point 4, but not right about the double counting part I think. The author is trying to calculate the actual cost of owning the Irish funds versus the US funds, adding the TER to the implied or DWT to be charged.
Anyway, agree on tracking error and bid-ask spread.

Think I made these points before somewhere, but can't find it. Anyway I'll try again.
1. Tracking error is overrated. It should be low, but comparing super low numbers becomes silly, especially since tracking error can be negative or positive errors.
2. Withholding tax rate for Ireland domicile is 15% not 20%
3. Bid-Ask spread is overrated. It's a one time cost, and the numbers are so small compared to the DWT that it's negligible.
4. From what I understand, the performance numbers for Irish domiciled funds are already net of the DWT, since the tax is paid by the fund managers. I believe US domiciled funds performance are gross of DWT, since the tax is withheld by your broker when the dividends from the fund are being paid out to you. I may be wrong about this, hopefully someone else (BBCW?) can confirm or correct. This means the blog post is double counting the DWT for the Irish and Lux domiciled funds.
IMO, I think the blog writer was mostly coming up with BS excuses to try to justify an obvious mistake their robo made during inception instead of doing the right thing which would take a lot more effort.
