This is the first time I’ve ever seen the 1815 Tambora eruption listed as a supervolcano, even a small one.

From WiKi:

Tambora erupted in 1815 with a rating of seven on the Volcanic Explosivity Index, making it the largest eruption since the Lake Taupo eruption in AD 181.The explosion was heard on Sumatra island (more than 2,000 km or 1,200 mi away). Heavy volcanic ash falls were observed as far away as Borneo, Sulawesi, Java and Maluku islands. The death toll was at least 71,000 people (the most deadly eruption of all time), of whom 11,000–12,000 were killed directly by the eruption; the often-cited figure of 92,000 people killed is believed to be an overestimate. The eruption created global climate anomalies; 1816 became known as the Year Without a Summer because of the effect on North American and European weather. Agricultural crops failed and livestock died in much of the Northern Hemisphere, resulting in the worst famine of the 19th century.

Suppose I was having trouble proving super volcanoes ever occurred. It would be tempting to look back on the limited records at hand, pick out a big one, and move the definition to accommodate my theory.
