[NSRCA-discussion] Resistance and retirement

[Vicente Bortone]

I use TP.  The IR is usually around 2-3 when new.  I usually use them for
practice and contest until around IR gets around 5.  Over 5 I start to feel
the power loss and I don't use those anymore.  I don't like to take the
smoke risk.  In general, I get around 80-100 cycles.
