It is my goal to always provide current charts. The way they come from the FAA is as 200dpi TIFF files. Uploading, scaling, and tiling is a process that takes days and results in 2.4 Gigabytes of tile images. This last month, I had the new charts up on the 27th, which was 5 days past the the issue date of the 22nd. I hope and wish to do better, but I think that 5 days is probably what you can come to expect.
