FFmpeg's -bt (Bitrate Tolerance) options...?

I want to encode video for Tablets and Mobile Phones by FFmpeg, is it important to set the '-bt' option?? If I just skip this option, does this affect the video playback on the devices??

‘-bt tolerance’ Set video bitrate tolerance (in bits, default 4000k). Has a minimum value of: (target_bitrate/target_framerate). In 1-pass mode, bitrate tolerance specifies how far ratecontrol is willing to deviate from the target average bitrate value. This is not related to min/max bitrate. Lowering tolerance too much has an adverse effect on quality.

Thanks!!

If you're using libx264 to encode, then the answer is "no" because -bt has been removed as a libx264 option last time I checked. See Remove bitrate tolerance from libx264 interface for the commit details.
