There are times when a scribe curves his writing so much that a RESH appears to resemble a KHAF instead of a RESH. If the curvature is extreme to the point that it shows a slight MOSHAV, it appears to me that a SHEELAT TINOK is not necessary as then it's obvious that the letter has lost it's shape. Nevertheless, it is possible that there will still be those who totter in their perception as in the above RESH's. The letters will at times appear to them as a RESH, and at others as resembling a KHAF.
Please weigh-in. Would you off-the-bat invalidate the above RESH's or require a SHEELAT TINOK?
