How can increasing the max of SALT deductions from 10kUSD to 72.5kUSD cause an average tax cut of 145kUSD for the top 0.1% earners (>1MUSD) in the US?

Question

I read an article from Fox Business (mirror 1, mirror 2) about the proposed change to the State and Local Tax (SALT) deductions:

• Under the latest proposal currently being considered by the House Rules Committee, the [SALT] deduction cap would rise from $10,000 to $72,500 for five years (it would be retroactive to 2021). The measure would then extend the cap through 2031.
• A separate analysis conducted by the Tax Policy Center shows that households earning at least seven figures a year would receive the majority of the benefits. About 25% of the benefits would go to the top 0.1% of U.S. households, which would receive an average tax cut of $145,000, while 57% would benefit the top 1%, which would see an average cut of $33,100.

How can the increase of the SALT deduction cap from 10kUSD to 72.5kUSD yield an average tax cut of $145,000 for households earning at least 1M USD a year?

When I do the maths, assuming an individual earning 2M USD via W2+cap gain+dividends in 2021 in the US state with the highest state taxes (viz., California), I get the following:

• 699,839 USD of federal taxes without SALT, standard or any other type of taxable income deductions.
• 239,921 USD of state taxes.

After deducting 72,500 USD of state taxes from the individual's 2M USD income, 2,000,000-72,500=1,927,500 USD, which will get 673,014 USD of federal taxes. The SALT deductions gave them a tax cut of 699,839 USD - 673,014 USD = 26,825 USD, which has nothing to do with the average tax cut of 145,000 USD that the Fox Business article claims. What did I miss?

Answer 1

The 145kUSD tax cut assumes that the SALT deduction cap is removed, and not increased to 72.5kUSD as Fox News incorrectly wrote.

Source (mirror 1, (mirror 2):

Who would benefit from removing the cap on the SALT deduction? The rich – especially the very rich. Almost all (96 percent) of the benefits of SALT cap repeal would go to the top quintile (giving an average tax cut of $2,640); 57 percent would benefit the top one percent (a cut of $33,100); and 25 percent would benefit the top 0.1 percent (for an average tax cut of nearly $145,000). The remaining four percent of the benefit of removing the cap would go the middle class (i.e. middle 60 percent), for an average annual tax cut of a little less than $27.

Also worth noting, this is an average and not a median. The median is certainly much lower.
