Yes, the "can go as high" statement should point to month 1 (theoretically, all funds could be disbursed on day 1).
As for "Includes only interest and no principal until ..." I'd say "month 12" or "maturity." (Year 1 might be technically OK since you can use months or years, but I think month 12 is much more accurate and I don't like combining months and years in the same table item).
