That's all over the last 2 years. Market low was apparently Dec 2018, before the Fed started cutting interest rates, so the numbers are a bit bigger since then. They were pretty steady through 2017-2019, so anyone who got grants or refreshers during those time periods has benefitted from that appreciation.
