I believe they are, but not perfectly so. That's because I don't think the ratio of points/dollar remains constant across the board. However, as a general rule, it seems the points/dollar ratio is 35.5/1.
• But on days when Saver Coach fares are offered, that ratio is higher because it seems like points are charged on the basis of the next higher bucket or the Value Coach fare
• For sleeper fares, that 35.5/1 ratio holds true except when it doesn't hold true. F'rinstance on tomorrows CONO from CHI to NOL, the Bedroom fare for one adult is $534 or 37, 914 points for a ratio of 71.0/1 - twice the norm. But for the next day (4 Jan) the ratio is back down to the 35.5/1 norm.
But perhaps someone else has a better answer for you. AGR points have always mystified me.
[edit] Re-checked the CONO fares this (next) morning of 3 Jan 2022 for travel today and the same situation exists. Bedrooms are still 37,914 points and even worse is a Roomette for 50,481 points, as shown below:
The Coach fare is also terribly inflated because the Value fare is $138 which at the customary 35.5/1 ratio would be 4899 points. But after this initial selection, if a different accommodation is selected and a return made to Roomette, the point values in the box to the right of the illustration appear to return to normal while that inflated "Rooms from 50,481 pts" figure remains the same. That 50,481 point cost shown above works out to $1422 which is more than four times the high bucket!
Tried a dummy booking to see if Arrow would actually charge me 50,481 for a Roomette, but didn't have enough points to proceed with the transaction.
Anyhoo, this might be the only time anything like this has ever occurred. Then again, . . . . .
