### Period recognition of linear growth in apgv5

I had previously noticed that the p42 guns for a glide-symmetric p8 ship in B2c3ai4rw5a/S23-a4ir was wrongly identified as yl84. One such gun is shown below:

Code: Select all

``````x = 8, y = 25, rule = B2c3ai4rw5a/S23-a4ir
4b3o4\$4bo\$4b2o\$5b2o\$4b2o10\$4bo2bo4\$o\$o5bo\$o4b3o\$5bo!
``````
Even more troublesome is B2ce3-ci5y/S2-c3-a, which has a p190, mod95 gun that fires p48 ships. This (quite common) gun registers as yl4560 and makes apgsearch very difficult, if at all possible:

Code: Select all

``````x = 7, y = 3, rule = B2ce3-ci5y/S2-c3-a
b2ob2o\$o5bo\$b2ob2o!
``````
This seems to happen only with guns for higher-period ships. The following gun for a p2 ship correctly registers as yl17 in the rule's census:

Code: Select all

``````x = 4, y = 3, rule = B2c3aeny4a5i6i7e/S12a3ejry4etz5y6c8
o2bo\$b2o\$o2bo!
``````
I have not encountered such difficulties with puffers.

Code: Select all

``````x = 4, y = 3, rule = B3-q4z5y/S234k5j
2b2o\$b2o\$2o!
``````

There's a puffer in highlife that produces the p10 so even though it has a fairly low period its apgcode is wrongly suggesting it has a period of several thousand gens.
