+The Suggested fit part is based on:
+* all skills on level V
+* as many Expanded Cargohold II as needed to get the cargohold capacity over 5,000{{m3}}
+* fitting all remaining low slots with Inertial Stabilizer II
+* fitting all possible Hyperspatial Velocity Optimizer II rigs
+Racial industrial bonuses for all ships in the table are:
+* 5% to cargo capacity per level
+* 5% to inertia modifier per level
+All ships have 3 medium rig slots and 400 calibration.
+=== Stacking penalty ===
+According to [[Stacking penalties]] the following numbers are in effect:
+* 1st mod: 100.0% effectiveness
+* 2nd mod: ~86.9% effectiveness
+* 3rd mod: ~57.1% effectiveness
+* 4th mod: ~28.3% effectiveness
+* 5th mod: ~10.6% effectiveness
+* 6th mod: ~3.0% effectiveness
+== Suggested fit based on Sigil ==
+=== Warp speed ===
+* Base warp speed 4.5AU/s
+* Hyperspatial Velocity Optimizer II
+** Warp speed bonus 25%
+** Stacking penalty in effect
+** cost 75 calibration
+Based on this we can fit 3 Hyperspatial Velocity Optimizer II
