Limitations of battle history download via CSV Export

Hi! I want to export my battle history (later my whole clan) of the last 3 month with the csv export to analyse it. But there is only a dataset with entries of the last 2 days available. What can I do?

You can’t. Supercell API only provides battle logs up to the last 25 battles.

I have forgotten: First of all - Great work at royaleapi! Love it.

My question: Which card combination do I lose most often? I start with wicon, then wincon and second card etc.
So if I want a bigger dataset for analysis I (everybody) have to merge the different csv files. Delete doubles.
No other way?

Use analytics under player info for cards analysis. If you want to do analysis for a lot of people then use the Supercell API directly.
