Re: (TFT) Rates of Fire



From: Michael Taylor <MichaelTaylor1@compuserve.com>

Excuse the formatting, but this really does line up correclty
in my text editor.


Michael,
I have edited the tables a little. Just to try and force them to line up. To that extent I trimmed the decimials. My comments are at the end. They are divided into three sections as outlined.
   1) Making sure I understand
   2) Pointing out what might be errors
   3) Making a suggestion to extend the first table



I'm comparing real-world characteristics to appropraitely translated TFT
Rate of Fire and modern weapons come out to be surprisingly playable
without having to drop their capabilities noticeably.

I'm very interested in any comments or suggestions.

RATE OF FIRE  Is calculated by taking the rpm (rounds per minute) and
dividing by 12 (12 turns in a minute). The percentage of variation
detemrines the specifics of the ROF.

AUTOFIRE WEAPONS  At this point weapon fire becomes so fast its impossible
for any human being to selectively fire the indivudal bullets. Any rpm of
60 or more must be fired from an Autofire weapon. These weapon fire
bursts of bullets in groups of 3 to 5 rounds. At this point we are
measuing how many BURSTS per round can be fired.

______________
1) Making sure I understand
So if I have this right; one can tell if a specified ROF is going to have a DX bonus based on the decimal. That is to say, after dividing the ROF by 12, if it doesn't fall on an even quarter (1/4 - 1 or .25 .5 .75 1.0) incriment then there is a ROF bonus. An increase of the ROF by one. In example here is a small section of the table.

SAMPLE        TFT ROF                 (rpm/12)
ROF
6             1/2                      0.5
8             1/2 (1/1 if DX 14)       0.66

    What I'm seeing here is that 0.5 is a precise 1/2 ROF.
    The 0.66 denotes a 1/2 ROF with a ROF bonus.

The second example is take from the Autofire weapons. Even though the decimal show is that produced by dividing by sixty, the ROF bonus is still based on the decimal produced from dividing by twelve. Take this instance.

AUTOFIRE  TFT ROF (BURST/ROUND)   (rpm/60)
ROF

128       2/1 (3/1 if DX 9+)       2.13

    On the first table this number 2.13 gives #/# with no ROF bonus.

Rpm/12                          TFT ROF
0       to      8.33            #/#

If the number is divided by 12 though it does. 128 / 12 = 10.66. This matches the results on your Autofire table.

Rpm/12                          TFT ROF
8.34    to      16.67           #/# (#/# if DX 9+)


______________
2) Pointing out what might be errors
I notice that on the second table you have ROF bonuses for decimals that don't appear on the first table. For instance, take my first example. The decimal 0.66 falls in the #/# only category. To get a ROF bonus for DX 14 it would have to be around 41.67.

SAMPLE        TFT ROF                 (rpm/12)
ROF
6             1/2                     	0.5
8             1/2 (1/1 if DX 14)       0.66

Rpm/12                          TFT ROF
0       to      8.33            #/#


______________
3) Making a suggestion to extend the first table
The first thing I see is a need to extend the first table. So it includes ROF bonuses for the lower decimals. Like this.

Rpm/12                          TFT ROF
0       to      0.33            #/# (#/# if DX 24)
0.34    to      0.5             #/#
0.51    to      0.67            #/# (#/# if DX 14)
0.68    to      1.25            #/# (#/# if DX 12)
1.26    to      1.75            #/# (#/# if DX 18)
1.76    to      2.083           #/#
2.09    to      2.5             #/# (#/# if DX 15)
2.56    to      2.67            #/# (#/# if DX 17)
2.68    to      2.91            #/# (#/# if DX 19)
2.92    to      3               #/#
3.01    to      3.25            #/# (#/# if DX 12)
3.26    to      3.33            #/# (#/# if DX 13)
3.34    to      3.75            #/# (#/# if DX 18)

Now, if I went to far in the wrong direction, just disregard all this. If I decifered this correctly, on the other hand, then the number spreads may need to be adjusted. Also, I notice that on this table extension the general rule of falling on and even quarter (1/4 - 1 or .25 .5 .75 1.0) breaks down. I'm sure the table could be tweeked to allow for that.
