yeh that sounds similar to my problem using the tach signal. glitches in high rpm.
what you say about r10 is correct. it still has some effect though, a number of people have reported it helping. By putting the resister b4 dave cap you are making an RC filter and changing the value of either R or C will effect the filter cut off frequency. but r10 is probably just effecting the amplitude of the signal, which then affects when the john diode conducts??.. anyway best way is to try things like you have.
yeh i was impressed with my RA40 tacho aswell, accurate right up to a tad over 7000rpm 
cheers
Chris
