How long does it usually take to burn all item and is there any record tools for progress after lv.60?

[NeoArcturus]

There are some userscripts for keeping track of that. Here are some that come to my mind rn:

• [Userscript] Enhanced Levels Overview
• [Userscript] Burn Progress
• [Userscript] Total Progress Bar (Allows Level Progress Removal)(aka 2Cool4Progress)
• [Userscript] Wanikani Heatmap
• [Userscript] SRS Distribution Charts

There is also a summary page script.

And congrats on reaching level 60

Not sure how long it will take you, but at least 6 months from now. AFAIK it takes many people multiple years to burn everything, though.
