SR X freeware climb procedures and "Dipsy Doodle":
Although this info is in the manual, I'm putting it here in a different form in case this is more convenient and concise for you.
If you "do the dipsy" manually, you only need a grasp of the principle.  The object of the detail below is to help you control the autopilot for a smooth procedure.

The SR uses two "Schedules" for climb:
400 KEAS and 3500 ft/min.
450 KEAS and 3000 ft/min.

They BOTH use the "Dipsy" for initial acceleration and result in Mach 3.0 at 72K ft at the climb rate of 1500 ft/min.
The 400 schedule results in faster climb at a slower mach speed using less fuel.  Used in the real world well away from the enemy incursion areas when you have longer distances to travel and want to conserve fuel.

The 450 climb achieves M 2.0+ much faster but at a more gradual climb rate using a little more fuel.  Used in the real world when pilots have to refuel near the mission danger zone and getting up to speed sooner is more important and refueling assets are close by.

The purpose of the Dipsy Doodle is to accelerate through Mach 1.15 much sooner.
Altitude history looks like this:
                          - cruise
                       _
                     _

In the descriptions below, note the differences between KIAS in the Airspeed gauge and KEAS in the Triple gauge.
Note1: At no time during the climb should the IAS drop below 400 KIAS.  If so, the problem should be corrected (no AB? wrong speed set in AP?) and the "Dipsy" started again.
Note 2: At lower fuel loads, the pilot may sometimes elect to power straight up through 28K ft without the Mach 9.0 cruise stage and not perform the "Dipsy":
Crossing 28K ft at M 0.95, set a gradual climb rate of ~ +1000 ft/min and IAS bugs of 470/530 until reaching the speeds of 420 (for the 400 KEAS schedule) or 450 KIAS (for the 450 KEAS schedule) then follow the rest of the procedure (see oooo below) increasing climb rates to the hold engage speeds of +2500 @400 KIAS or +2000 @450 KIAS.

Dipsy Doodle (same for both 400 and 450 schedule, AB On):
Subsonic cruise ~ 28K ft Mach 0.9.
Accelerate to M 0.95.
While passing through M0.92 start +3500 ft/min climb with ALT HOLD set to 35,000 ft.
By 34,000 ft, climb rate should be down to +1000 ft/min.
Crossing 3400 ft Set ALT HOLD to 31,000 ft, Descent Rate to -2000 ft/min.

400 KEAS schedule (faster climb, slower speed):
o Set IAS bug to 470 KIAS.
o Crossing through 400 KIAS, set Descent Rate to -1000 ft/min. (from -2000.)
o Crossing 420 KIAS, set ALT Bug to desired cruise altitude (typically 79K or 80K ft, or as required by weather.)
o Increase Climb Rate bug to +2500 ft/min.
o Watch KEAS display in Triple gauge carefully with mouse over KEAS HOLD.
o As KEAS speed crosses 400 KIAS without display blinking, click on KEAS HOLD button (middle) in the refuel gauge.
o Increase climb rate to +3500 ft.min.
o As altitude crosses 51K ft, decrease climb rate by 1000 ft/min per 1000 ft of climb.
-> GOAL is +1500 ft/min at 70K ft. Mach 3.0 by 72K ft. Fuel rate of ~ 2000 lbs/engine is typical.
o As Mach speed approaches 2.85 to 2.90, set mach speed bug to 3.10.
o As IAS speed lowers to near 400 KIAS, reduce climb rate and increase mach speed to
o obtain desired mach and altitude target (typically M3.2 ~ 80K ft or as required by weather.

450 KEAS schedule (slower climb, faster speed):
o Set IAS bug to 530 KIAS.
o Crossing through 400 KIAS, set Descent Rate to -1000 ft/min. (from -2000.)
o Crossing 450 KIAS, set ALT Bug to desired cruise altitude (typically 79K or 80K ft, or as required by weather.)
o Increase Climb Rate bug to +2000 ft/min.
o Watch KEAS display in Triple gauge carefully with mouse over KEAS HOLD.
o As KEAS speed crosses 450 KIAS without display blinking, click on KEAS HOLD button (middle) in the refuel gauge.
o Increase climb rate to +3000 ft.min.
o As altitude crosses 56K ft, decrease climb rate by 1000 ft/min per 1000 ft of climb.
-> GOAL is +1500 ft/min at 70K ft. Mach 3.0 by 72K ft.  Fuel rate of ~ 2200 lbs/engine is typical.
o As Mach speed approaches 2.80 to 2.85, set mach speed bug to 3.01.
o As IAS speed lowers to near 400 KIAS, reduce climb rate and increase mach speed to
obtain desired mach and altitude target (typically M3.2 ~ 80K ft or as required by weather.

It's best to practice the 400 KEAS climb before the 450 KEAS climb as with the later, events happen much closer during the Dipsy Doodle.  Once KEAS Hold is engaged, the rest of the climb is easy going.
Note: The KEAS hold function is optimized for the two speeds of 400 and 450 KEAS.  Setting the hold at other speeds may cause unpredictable behavior (outside +- 5 knots of these speeds.)  If you miss the target by more than is acceptable (setting faster than 450 KIAS may result in overspeeds) disengage KEASE hold by clicking again, adjust your airspeed and try again.
After trying it once or twice, you'll get it every time from then on.
