OK I've had an epiphany. The speed to input for the above methods can be easily computed using the rear side of the attack disk (click in the middle of the front side to flip it over) included in TDW's UI within TWOS.

For the first method (Ausdampfverfahren), get speed for TDC by aligning own speed (middle numbers within middle ring) with 90 deg mark on outer ring (right at the top). The speed that intersects the outer ring at the collision bearing is the speed to input.

For the second method (Auswanderungsverfahren), same procedure as above, but to this result you must add/subtract correction (d) as we know. To compute this correction, align range at 1st bearing (E) with 90 deg on outer ring. Then align 1-00 on the "Zeit" disk (or longer if we waited more than a minute) with the change in bearing (w) on outer ring. Read speed correction at the red index line. Should be noted that you need at least 6 deg of bearing change to use the disk. Therefore wait as long as you need to get that change; just be sure to note the exact time you waited and align it with the bearing change on the outer ring.

No need to take eyes off the game with this method. Please share your thoughts/success!
