Brad:
It stands for "larger than resonant". (1.57 x Cresonant value)
If you calculate the impedance match between a NST and capacitor
value, there is one value at which he impedances match, ie
"resonant". This produce max energy transfer, however, a resonant
condition may ensue between the NST and this capacitor value which
could damage the xmfr even with a protective circuit.
The LTR term is derived by multiplying the impedance matched
"resonant value", Cres, by 1.57 to obtain the max LTR value a xmfr
can charge the cap in a reasonable amount of time, ie, so it reaches
full charge before firing at the next plus or minus peak on the 60 Hz
waveform (120 plus/minus peaks per sec).
Terry Fritz has published the correct LTR values in the archives to
match NST with proper capacitor value.

Hello all,
Having been inactive for several years I have seen mentioned LTR
caps in the archives and some websites. I would like to learn more
about this practice. Can someone recommend a website or source of
information on this topic?
