HP 15c CE - New firmware update officially available!

[Johnh]

rI havnt updated yet, but I'd have thought 120ms would be fine, it amounts to more than 8 inputs per second. Even just between a couple of the same digits, I can't put them in faster than about 5 per second and wouldn't expect to be reliably able to do so.

In terms of missing digits, I find that a more common cause is from buttons lightly pressed, particularly if part of the finger or thumb tip or nail contacts the case or other keys It's possible to get the initial 'breakaway' feel of depressing the key, but not quite achieve the 'click' to enter the digit. The most common way this seems to occur is when hand-holding the calculator rather than placing it on a desk, and keying in with thumbs. It's a classic way to operate a Voyager and different to other calculators which are in a vertical format.
