Using probe that started losing B1 strength or has longer 90 degree pulse

I've found that one of our probes lost ~1.5-2 dB of power on 13C, but nutation curve looks OK. There are no random spikes in the intensity of the peak seen on arcing probe. So I assume there is no "serious" arcing.

Is it OK to continue using it with a bit longer 90 pulses and slightly higher power for decoupling till arcing becomes a real issue or have it serviced right away?

Thanks.
