Since the Nelnet connection is broken I am tacking my student loans manually. I updated the balance once in November and again in December. I would expect that my net worth would only change by the amount changed between November and December, but instead it shows that I have 10 years of the loan at the full amount (that was when I said it started), then it suddenly drops to the value I reported in December. It should at least use the November data point to estimate the change in my net worth this month, not the total loan amount compared to now.
