T' NARRRRR uses a bewilderin' number o' acronyms t' describe its contests. Blimey! As with most things o' this nature, thar be a logic t' t' namin' which makes things much easier t' understand once learned. Avast! 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, matey, such as parachute duration, arrr, have t' suffix "built in" t' its name, thus don't use one). A futher appendage be t' use o' "MR" for "Multi-Round" events where you make several flights and pick t' best ones. Begad! 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. Aye aye! For this reason, t' prefixes are normally separated from t' event acryonym by spaces.
