I was thinking of the different speed settings on the torpedo if that would make a different in lead angle to shoot at.

A faster torpedo reaches the target quicker. Which gives the target less time to move forward. So the lead-angle is proportionally smaller. The 44 knot setting is about 50% faster than the 30 knot torpedo. The lead angle is (with same target speed and AOB) then about 2/3rds (1/1.5) of the leadangle of the 30 knot torpedosetting.
Rockin Robbins does the 90 degree (or 45)
minus leadangle by himself because SH4 doesn't do that automatically. SH3 however does when the TDC is set to Auto! In step 3 to 8 you setup the TDC for a simple situation with the bearing a 0 and AOB at 45 (or 90). To simulate the target being right in front of you. But this makes the torpedo turn a bit to the side. To correct this, at step 9 you must turn the periscope and make the gyro-angle 0. Now the AOB is adjusted automatically (because the TDC is in Auto mode). So the AOB indicator wil show 45-leadangle (or 90-leadangle) when the periscope readout shows only the leadangle. And the torpedo moves straight ahead.

... I figure the better I am at shooting with a 45 or a 90 degree AOB. The more choices I have at my service to sink ships. The better I will become.

YES!!! That's the spirit!
