1500 points is enough to process 7.5 gigapixels worth of imagery. For a 20 megapixels camera this would be roughly 375 images.
62 images should only be 1.24 gigapixels worth of imagery. The first one would be free so you really don't even need 50 points to process 62 images.
Can you please share a screenshot of the calculation part of the uploader?
