Your sample is the thing that makes any stat meaningful, so switching tools should never mean starting from zero. CSV import maps your columns once and brings the whole history across.
Point your existing export at the importer, map the columns a single time, and your sessions and bankroll history come across. Your variance and win-rate stats are useful from day one, not month three.
From a spreadsheet or an old tracker
Whether you are leaving a spreadsheet or an older results tracker, a CSV export is the bridge. The import preserves the dates and figures, so the sample stays intact and your hourly stays honest.
No lock-in, ever
What comes in can go back out. Overshove exports to CSV any time, so your data is never trapped, the same ownership a spreadsheet gives you, without the manual upkeep.
What you get

→Works from spreadsheets and older trackers.
→Preserves dates and figures so stats stay honest.
→Export back to CSV any time, no lock-in.
How this fits the review loop
This feature earns its place only if it makes the next session cleaner. The Overshove loop is deliberately small: log the session, read the number beside the sample, mark the useful hand or leak, then carry one action into study. If a feature cannot support that loop, it stays out of the way.
Judge it with your own data. A strong feature should reduce skipped sessions, make a cost visible, stop a bad stake decision, or give your coach a cleaner packet. Pretty charts are optional; a decision you can defend is the point.
Questions
What format do I need?
A CSV export from your current tracker or spreadsheet. You map the columns once during import.
Will I lose my history switching?
No. That is the point of the import: you keep the full sample, which is what makes your stats trustworthy.
