Recently active topics in AideRSS tagged with max-results

I have this BlogSpot blog and they always restrict the number of posts they give in the RSS to 25. But there is a way to get them all like this: http://myblog.blogspot.com/feeds/post... I tried it in AideRSS and it returns an error. I finally found that using 500 instead of 1000000 worked, but still it didn't import all my posts. I would love to use and promote your service, but since my best posts are older, there is no real use of displaying just the latest good reading.
