T' NARRRRR uses a bewilderin' number o' acronyms t' describe its contests. Begad! As with most things o' this nature, thar be a logic t' t' namin' which makes things much easier t' understand once learned. T' basic structure o' an event name is a prefix, t' event acronym and a suffix. Begad! T' prefix is always t' motor code (currently 1/4A thru G) and t' suffix is either an "A" for altitude events or "D" for duration events if such a distinction needs t' be made (some events, such as parachute duration, shiver me timbers, have t' suffix "built in" t' its name, shiver me timbers, thus don't use one). Ya scallywag! A futher appendage be t' use o' "MR" for "Multi-Round" events where you make several flights and pick t' best ones. Ahoy! Event Acronyms:
BG - Boost Glider
DEL- Dual Eggloft
DR - Drag Race
EL - Eggloft Single
FW - Flexwin' BG
HD - Helicopter Duration
OSL - Open Spot Landing
PAY - Payload
PD - Parachute Duration
PMC - Plastic Model Conversion
PRA - Predicted Altitude
PRD - Predicted Duration
PSL - Parachute Spot Landing
R&D - Research & Development
RDA - Random Altitude
RDD - Random Duration
RC/RG - Radio Controlled Rocket Glider
RG - Rocket Glider
SC - Scale (often seen written out)
SCA - Scale Altitude (sometimes seen as Sc.Alt)
SD - Streamer Duration
SL - Spot Landing
SPSC - Sport Scale
SPSY - Space Systems

STA - Set Altitude
STD - Set Duration
SUSC - Super Scale

Note that thar be an ambiguity in t' Eggloft event notation. "DELA" could mean t' generic Dual Eggloft Altitude event or D Eggloft Altitude. For this reason, t' prefixes are normally separated from t' event acryonym by spaces.
