Dear SEC,

This is some summary data to back up my conclusions that leveraged ETFs are a good option for me as a long term buy.

Assuming that I had invested $100,000 dollars each year over a thirty year period from 1950 to 2015 in the UPRO, I would have made approximately this much money:

5th percentile: 4.8 M
25th percentile: 50 M
50th percentile: 170 M
75th percentile: 500 M
95th percentile: 1.3 B
average: 310 M

This is adjusted for inflation estimated at 3.4% and an expense ratio of 0.95%. 
It also assumes zero tracking error, fractional shares, and investing an equal amount of the $100,000 every trading day of the year at the opening price.
This is a very good return on the 3M dollars put into the investment over 30 years.

If I had invested this much into the S&P 500 instead, I would have made about this much money:

5th percentile: 6.4 M
25th percentile: 8.9 M
50th percentile: 11 M
75th percentile: 16 M
95th percentile: 24 M
average: 12 M

This assumes reinvested dividends of 3.6% per year and zero expense ratio.

I can send the code used to do these calculations, or answer any questions about my assumptions.
