Yes, precisely. Make the blend area shorter and steeper, which perforce makes the inner tip a little longer. If this causes the pitch to drop below C, you clip a tiny fraction, and refine the extreme tip again. This does not usually happen to me.
This is one of the most delicate areas of a reed, and so must be done with the sharpest of knives, and by "dusting", not "scraping". If you remove anything bigger than dust, you are going too fast! I test the crow after adjusting each side to keep my scrape pace down to a crawl.
I have also seen an Eastern European scraping technique that can be useful for this particular area. The reed is held with the tip and plaque facing you, staple pointing away from you. The reed is supported with the LH Middle and Ring fingers, and RH Thumb under the tip (assuming you hold the knife with your right hand). The scraping motion is made by curling the fingers round the handle. The scraping angle is done by adjusting the angle of the reed. You need a razor knife with the burr set backwards, since you are scraping in the opposite direction. One stroke on your stone.
The advantage of this technique is that you are viewing the tip from a much better angle while scraping, and can make much more accurate adjustments.
