If I enter this way I (and our clients) get too big depreciated value per month:
In the Asset record:
purchase date=2012-12-13, start date1= 2013-01-01, asset value € 5796.17, model=120 (120 months=10 years), straight line, residual value=0.00

Revaluation record:
Asset life is not changed (120 months), new percentage for the model is calculated according to the formula in hansamanuals.com.
transaction date=start date1=2017-03-01
model=17_14 (17.14%/year)
new start value1 =5796.17+559.8 =6356.05

depreciation per month should be about 50+ euros/month, the report shows 90+ €.
