Spelled-out — seventy-thirty asymmetric leg entanglement
Seventy-Thirty is the spelled-out form of the 70/30 leg entanglement — the asymmetric configuration in which one player has roughly 70% of the leverage advantage and the other has 30%.
Etymology. “Seventy-Thirty” is the spelled-out version of “70/30”; both refer to the same asymmetric position. The compound predominates in spoken vocabulary.
Mechanics. The asymmetric configuration favours the higher-leverage player — the lower-leverage player works to escape or rebalance.
Cross-reference. “80/20” and “Asymmetric 50/50” are alternate names. Full mechanical coverage on 70/30.
