derating MLCC ripple current for transient current spikes

This graph - MLCC temperature rise vs ripple current RMS & frequency

![Image_alt_text](https://electrical.codidact.com/uploads/by7ol4n57tsdnyh4q8lchyx1fl8d)

If I had a 10 us current spike every 100 000 us (akin to a half-sine wave and then the rest of 9999 sine waves missing), how much higher can i go in current ripple RMS value for the 20 deg. C max temp rise ?
