If you feel that the 5.8 setting, in eyepoint=55.0, -1.6, 5.8, is not high enough, just change it up/down by .05 at a time (i.e 5.85, 5.90, 5.95 etc.) until it gets close to what you want, then make any changes in 0.01 increments (5.86, 5.87, 5.89 etc.). If you want even finer tuning, make changes using 0.005/0.001 (5.805/5.806) increments. The size changes go on from there. ;D

This way you can have a different setting that suits yourself. ;)
