Is this Wyckoff guy correct with this? Dude is a real OG if so

Note: Springs or shakeouts usually occur late within a TR and allow the stock’s dominant players to make a definitive test of available supply before a markup campaign unfolds. A “spring” takes price below the low of the TR and then reverses to close within the TR; this action allows large interests to mislead the public about the future trend direction and to acquire additional shares at bargain prices. A terminal shakeout at the end of an accumulation TR is like a spring on steroids. Shakeouts may also occur once a price advance has started, with rapid downward movement intended to induce retail traders and investors in long positions to sell their shares to large operators. However, springs and terminal shakeouts are not required elements: Accumulation Schematic 1 depicts a spring, while Accumulation Schematic 2 shows a TR without a spring.
