90,000 / 5280 (feet in a mile) = 17 miles 3.14 * 17 ^ 2 = 912 Square miles (Pi R Sq - You do remember that formula, don't you?)
Using the same math, if you have the same engine failure at 1000 AGL, you still have a 16 theoretical square mile circle in which to land. Now, using that 95 MPH Best Glide speed and figuring your decent rate goes up to an estimated 700 FPM, from 7500 AGL you will be on the ground in 10.7 minutes. From 1000 AGL it will only take you 1.4 minutes to reach terra firma. With over 10 minutes to pick a spot in which to land from 7500' people still manage to bend metal or break plastic. Why is this?
Denial slows reaction time for a lot of us. "Oh, my engine couldn't have died" or some such thing. In the 30 seconds it took you to get past that, you have lost some altitude, say 350 feet. Now you are down to 7,150 feet.

Next up, trim for best glide. Do you know your best glide speed or do you have to look it up? Did you ever actually test your homebuilt? (BTW, my numbers are very close to what CAFE Foundation found.) If you bought your homebuilt, did you even bother to verify the numbers the prior owner gave you?
Ok you are trimmed and are now coming down at that theoretical 700 FPM. By this time you are down to 6,800 feet AGL and are starting to look around. You will be on the ground in 9.7 minutes and your landing area is down to 750 square miles.
