This chart I provided in the OP was received via email from Track Shack Events on August 2nd, 2018:

Here is the email correspondence:
Hi,
I'm a coach with several athletes participating in different Marathon Weekend events. I'm interested in getting more information about the Proof of Time cutoffs. Could you tell me the time necessary for each of the different submittable POT distances for the Half Marathon, Marathon, and Dopey that would equate to the necessary converted time?
For instance, for the Half Marathon - Could you tell me the necessary 10k, 12k, 15k, and 10 mile times that equate to a 2:45 Half Marathon using the race equivalency calculator you plan to use for the 2019 Marathon Weekend?
For the Marathon and Dopey (and whether they're different?) - the necessary 10 mile and HM time that equate to a 5:30 Marathon using the race equivalency calculator you plan to use for the 2019 Marathon Weekend?
This information will be helpful to me as I plan out my runner's Fall schedules and give them advice on how to proceed when submitting information for their POT.
Thanks in advance for any help you can give!
And their reply:
Hi William,
Thanks for your inquiry about the Proof of Time cutoffs to help your runners as they train for the 2019 Marathon weekend. Based on the race equivalency calculator that we will be using for the 2019 WDW Marathon and Half Marathon, below are the time cutoffs that equate to the 2:45 half marathon and the 5:30 marathon times. Note that for Dopey participants, we use the Marathon cutoff times.
As a reminder, races used as proof of time must be from an officially timed race reflecting results after January 1, 2017, and must be one of the distances listed above. Proof of time must be provided by October 9, 2018.
Please feel free to contact us if you have any additional questions.
Thank you,
Track Shack Events on behalf of runDisney

The other chart seen in the OP (seen below) is one I made using extrapolated values from other runner's conversions using what appears to be the runDisney standard calculation method. It is not perfect, but very close.
So based on the information that I have at this moment, I am being led to believe the HM POT cutoff using a 10k for corral E is a 1:15:00. I have no reason to believe at this time that Marathon Weekend was a unique calculation given Wine and Dine 2018 also followed the same calculation as far as I can tell. Although, if you can provide me a source for the discrepancy I'm willing to change the OP.
