I understand what you're saying about the ramifications of lost time in LotTL, but the discussion referenced Martha's intentions about her studies, claiming she abandoned her medical trainig to run-off with the Doctor.

Martha had no pre-knowledge accepting the Doctor's invitation in S&J, that she would be wandering the earth for a year, and prior to that she kept her studies mentioned in present tense. Even after Lazerus, she had only lost a couple days. Its reasonable that she had went into it thinking she would only have to recoup a days or weeks at most. No abandonement, her committment at the time occurred before she had to suffer any long-term downtime as seen in the later third of the season.
