Yet they did not bother creating any other scenes other than those using those rocks, i think its obvious its supposed to be a feat of strength, but not 1000+ ton strength, perhaps a few tons, just like the Zelda wikia points out but not that high regardless of math. Until I see Link actually use this strength for a variety of things other than tossing rocks ill simply base it on what it really is, an overestimated feat taken too seriously on an old and not necesserily accurate game.
