Tick Offset - % Calculation

[easyrtr]

Hi,
Can anyone tell the calculation Gruss makes on a Tick Offset with 30% tick change and Auto-level on

Im either doing the calculation wrong, or Gruss is telling me something different.
e.g. Back @ 6.8, with 30% tick change, lay bet is placed at 5.0
this is a percentage difference of 26.47% not 30%
My Calc: (6.8-5.0)/6.8 = 26.47%

The odds Gruss should have placed to get to close 30% is 4.8:
(6.8-4.8)/6.8 = 29.41%

Are my calculations correct?
