This might be your best bet until more tables become available.
I found this procedure to "speed up" the learning process. This may work on other transmissions also.
1) Start the engine, allow the engine and transmission to reach operating temperature with all accessories off.
2) Once operating temperature has been reached, idle engine for a minimum of 1 minute with all accessories off.
3) Idle engine for a minimum of 1 minute with the A/C turned on.
4) Drive the truck and allow the transmission to shift from 1st to 5th with light throttle input. Repeat the process at medium throttle input, and finally at wide open throttle (if permitted, always obey local traffic laws).
5) With the vehicle stopped and the gear selector in the N (neutral) position, perform the following series of gear engagements (the order is not important, but three different sets of gear engagements must be made):
Shift from neutral (N) to reverse (R), then wait a minimum 3 seconds
Shift from reverse (R) to drive (D), then wait a minimum 3 seconds
Shift from drive (D) to neutral (N), then wait a minimum 3 seconds
Repeat this sequence once more with the Tow/Haul mode activated. Following these procedures will potentially reduce the relearn time of the adaptive strategy system.
Something odd with this transmission is 4th gear ratio is only used during cold operation shift schedule - 5R110W normally shifts 1-2-3-5-6
