[Genome] how many chr location I may have in custom wig file?

[Khrebtukova, Irina]

Hi,
 
am I right that if I'm making custom track type=wiggle_0 in bed format
with 2 colors (for positive and negative values), like say:
 
track type=wiggle_0 name="Whatever" visibility=full autoScale=off
color=200,100,0 altColor=0,100,200
chr8 104060000 104070000 3
chr8 104070000 104080000 2
chr8 104080000 104090000 1
chr8 104090000 104100000 0
chr8 104100000 104110000 2
chr8 104110000 104120000 -1
chr8 104120000 104130000 3
chr8 104130000 104140000 3
chr8 104140000 104150000 3
chr8 104150000 104160000 2
chr8 104160000 104170000 2
 
am I right that in this case I can NOT put more than 25K chromosomal
locations into one track? (it seems exactly like this...)
 
though it's a bit strange because I was able so far to put MUCH more
chromosomal locations in simple BED tracks (just chr start end) as well
as simple WIG tracks (variableStep but fixed small span). 
 
is this your policy or I'm doing something wrong?
 
thanks! I appreciate your help and needless to say (I think it's
obvious) that your browser is the best! (I doubt anyone could argue...)
