TI-H: Turbo 85 problem



Well, its not actually a problem...
I have turboed 6 85s with a switch successfully and finish turboing one
yesterday. The one that I turboed yesterday is a rom version 10.0 and is
only several days old (off the shelf). I compared speeds of this new 85
with my own personal one (10.0 and 1 year old) and noticed that the new
85 is FASTER! I used the same batteries in each one and switched them
around a lot and I can't figure out why it is faster!!! The weird thing
is, is that it's faster in normal mode and turbo mode.
Here are my hypotheses:

1) Newer 85's are faster than old ones

2) I fried a cap while turboing (don't know which calc)

I don't know much about electronics, but let's say I fried the 1 pF cap
in the new calc. well when wired in parallel (normal) with a 33 pF cap,
normally it would result in 34 pF total capacitence. When wired in
series (turbo) the capacitence would be .97059 pF. Let's say the 1 pF
cap was fried. Would the normal capacitence be 33 pF and the turbo be
0 pF??? Please help me out with this one. If it's true that I fried the
1 pF cap and my logic is correct.  recommend not even using a 1 pF cap
because it is LOTS faster and I haven't seen any errors at all!!!

Just to get one thing straight...is Cp=C1+C2 ; Cs=(C1*C2)/(C1+C2)
correct? those are the formula's I used above.
