See the Why delaying Stutterwarp Discharge is rare article for explanation.
GDW's 0.645 AU/day Variant 6.45 AU/day Insystem Speed Constant ( Warp Efficiency 1.00 = ___ AU/day)
AU from the FTL Threshold to the destination world. Enter 0 if the destination planet is located outside the FTL Threshold. The average insystem distance for the French Arm colonies is 1.38 ( for the Sol/Earth system use 1.45 instead).
Hours needed to match the orbital velocity of the destination world before drive discharge can start.
Extra LY you want to travel beyond 7.7 LY, by delaying stutterwarp drive discharge.
Minimum speed ( WarpEff) required to make the voyage in exactly 24 hours ( with no time to spare).
