No problem.

You can see it e.g. here in restore.c :

        /// start restore image file to partition
        for( block_id = 0; block_id < image_hdr.totalblock; block_id++ ){
                /* doing things, copying the blocks */
            update_pui(&prog, copied, done);
        } // end of for


I did a patch for myself within I told it just call update_pui once for
5000 blocks. Don't know if its a good idea, but it worked ;)
