The FOCAL program was beginner level, i.e., not streamlined to stack-only operations.

By doing just that (using just the stack) a while back when I first benchmarked the DM41X, I got it to do 100 iterations in 3.85s when on USB power and in 12.09s on battery power.

I get slower times with coding that uses storage registers and the TIME function to compute the elapsed time, rather than a stopwatch:

LBL <t>SPEED
STO 10
TIME
HR
STO 00
0
STO 11
1
STO 12
LBL 01
ATAN
SIN
E^x
3
1/X
Y^x
ST+ 11
RCL 12
1
+
STO 12
DSE 10
GTO 01
TIME
HR
RCL 00
-
3600
*
END

My results are:

fast mode, battery powered: result=139.2971873, time 16.36 s

fast mode, USB connected: result=139.2971873, time 5.36 s
